INTRODUCTION

This service manual is intended to assist you in diagnosing conditions which maydevelop. Electrical component testing is for the most part, made with an appliancetest meter and consists of checking for open or closed circuits. Mechanical checksare made through sight and sound, along with the use of a clamp-on ammeter.

This manual is designed for the technician who is familiar with the operation andconstruction of Maytag products. Information contained in this manual is intendedfor use by a qualified service technician, familiar with proper and safe proceduresto be followed when repairing an electrical appliance. All tests and repairs shouldbe performed by a qualified service technician equipped with proper tools andmeasuring devices. All component replacements should be made by a qualifiedservice technician, using only MA yeOR replacement parts.

Improper assembly or adjustment may occur if service or repair is attempted bypersons other than qualified service technicians or if parts other than MA yeORreplacement parts are used. Improper assembly or adjustment can cause hazardous conditions.

There can be risk of injury or electrical shock while performing services or repairs.Injury or electrical shock can be serious or even fatal.

SECTION 1. ELECTRICAL TEST EQUIPMENT

The equipment required to serviceMaytag products depends largely uponthe condition encountered. Locating amalfunction will often require the use ofelectrical testing equipment such as:

• Appliance Test Meter

• Clamp-on Ammeter

• Motor Test Cord

APPLIANCE TEST METER

Probably the easiest means of testingelectrical components is ~'continuity

testing" with an Appliance Test Meter.Continuity is a complete or continuouspath from one point in an electricalcircuit to another point.

The obvious advantages of being ableto check electrical components and circuits without power applied is one ofthe features of the ohmmeter. Multipleranges allow accurate determination ofresistances of both single componentsand entire circuit paths. Resistance ismeasured in "ohms".

An Appliance Test Meter is a multipurpose tester combining an AC-DCvoltage tester with a multi-rangeohmmeter.

APPLIANCE TEST METER

SET METER FOR USE AS FOLLOWS:

1. Calibrate meter by touching testprobes together and turningadjusting dial until meter reads "0"on the ohm scale. Recheck calibration whenever adjusting dial forohms settings is changed. (Replacebattery if adjustment will not bringmeter reading to "0".)

2. Select the scale most easily readand place test probes on respectiveterminals. When checking a switch,the reading would normally beeither open or closed. A reading of70 on the R x 10 scale would forexample be 700 ohms resistance.

ED/GD401 1090 SECTION 1. ELECTRICAL TEST EQUIPMENT 1-1

~f~

~.,~"] QCAUTION ---------------,

Always be sure the power has beendisconnected before making resistance measurements. Failure to doso will result in damage to yourmeter! Internal batteries provide allthe power needed to make resistance checks. They should bechecked at least once a year andreplaced as needed.

For the most part, we will only be concerned with continuity. Is there a pathor not? References are made betweena "closed" (continuity) reading and an"open" (no continuity) reading. Onenote, when you get an "open" reading,try a higher resistance range (setting).A very high resistance appea~s as an"open" on the lower ranges. For bestaccuracy alw~ys "re-zero" meter whenchanging ranges and/or the physicalposition of the meter.

Continuity testing, as related to an elec-\

tricarcomponent, is the check of a partfor an "open" or "closed" circuit.

Electrical components fall into twogeneral categories.

1. Loads- Devices that use orconsume electricity: Examples

ED/GD401 1090

would include drive motor, heatingelements, lamps, timer and solenoidcoils.

2. Switches - Devices that control thesupply of electricity to the load orloads in a circuit. Examples includedoor switches, timer contacts,selector switch and relay contacts.

Continuity test of "load" devices willshow varying levels of resistance fromvery low for some transformer andmotor windings to very high for sometimer motors and components on electronic control boards. Usually it ismore important to know if there is apath for current .flow through a device(continuity) than to know the exactresistance (ohms) of the device.

Continuity tests of switches will showvirtually no resistance, even low valuesindicates burned or dirty contacts in aswitch.

Continuity testing is a process of eliminating those electrical componentsinvolved in a given function of theappliance, until the inoperative part isfound. By reviewing the list of possibleelectrical problems under a given condition, and then performing appropriatecontinuity checks on the parts involved,you should be able to locate the electrical component which is inoperative.

When checking components or circuitpaths for continuity, external wiringshould be disconnected to eliminatefalse readings through external paths.Isolate what you want to test.

The following shows typical resistancevalues for some of the componentsfound on Maytag dryers.

Heating Element -- 10.23 ohms.

SECTION 1. ELECTRICAL TEST EQUIPMENT 1-2

Gas Valve

Disconnect radiant sensor and igniterwires. Measure across igniter wires origniter plug from valve to get a resistance value of -- 425-450 ohms.

Measure across sensor wires to get aresistance of -- 450-475 ohms.

Drive Motor

Red terminal to Gray terminal -- 1.5ohms.

In order to measure the individualwindings the red and gray wires willhave to be pulled off of the start switch.

Run winding only -- 2.25 ohms.

Start Winding only -- 3 ohms.

Glow Bar Igniter

Because of the make-up of the igniter,the resistance will vary over a ratherwide range. Values from 180 ohms to400 ohms would be typical with anigniter at room temperature.

These values are provided so that youmay have an idea of the resistance thatyou can see in testing. These resistances are not meant to be used as theexact values to determine whether at;omponent should be replaced. They

\

are provided so that you may have anidea of the resistance that you can seein testing components.

EDIGD401 1090

CLAMP-ON AMMETER

Each circuit in an appliance has a"normal" current draw which is an indication of the performance of that circuit.Current draw levels, less than or morethan normal, give clues to malfunctions.The clamp-on ammeter measures thesecurrents without breaking the circuit bymeasuring the strength of the magneticfield developed around each conductor.Current is read by separating the conductors and clamping the jaws of theammeter around each conductor onwhich current is to be read. Lowamperage readings indicate problemssuch as damaged heating elements,etc. High amperage readings indicatethe unit being tested is operating underan increased mechanical or electricalload.

SECTION 1. ELECTRICAL TEST EQUIPMENT 1·3

Note: Overloads on a circuit breakeror fuse can be traced to the productbeing tested or the circuit breaker (orfuse) by checking the product's currentdraw. If the amperage reading is lessthan the breaker reading, the breakeror fuse box is at fault.

USE OF AMMETER ON DRYER

There are two currents of concern to usin an electric dryer; the heatingelement current and the drive motorcurrent. These currents can be measured by use of a "split line cord" extension for the dryer cord or by attachingthe ammeter to the respective powerline wires at the dryer terminal block.Current measured should be 21 ampson the heating element side of the line,24 amps on the drive motor side of theline and 4 amps on the center orneutral line.

MOTOR TEST CORD

The motor test cord may be used. toelectrically check operation of the drivemotor while still installed in the unit.Testing of the motor in this mannerdetermines whether or not it will runindependently of other electrical components.

Two test leads are required to checkoperation of the drive motor. To checkthe motor for running, hook up testcord as shown.

VOLTAGE CHECKS

For the most part these checks willconsist of taking readings at the wallreceptacle in order to delermine theavailability of voltage to the product.Voltage checks on individual components of a product are not recommended due to the possibility ofelectrical shock. Component parttesting is best accomplished throughcontinuity checks with an ApplianceTest Meter.

Note: Use of the meter on voltagehigher than the indicated range maycause permanent damage to the meter.To prevent damage, first select highestrange for readings which fall within thelower scale.

SET UP METER FOR USE AS FOLLOWS:

1. Turn selector knob to desired meterfunction and appropriate range.

2. Plug black lead into socket marked (negative).

3. Plug red lead into socket marked +(positive).

4. Place test leads into receptacle inorder to determine voltage available.

ELECTRONIC CONTROL MODELS

The electronic control and timer areused to complete the drying cycle andcool-down period for these dryermodels. The dryer starts out with thedrive motor running, the timer motorrunning, the heat cycling and the electronic control disabled. As the timeradvances to a certain point in the cycle,

CAUTION -------------------------,


ED/GD401 1090 SECTION 2. ELECTRICAL - MECHANICAL TROUBLESHOOTING 2-2

the electronic control becomes operational as cam number two opens. Ashort time later, the timer motor is deenergized when cam number one forthe timer motor opens. It is during thisstall period that the electronic controlsystem uses the wet clothes fallingacross the sensor in the drum to discharge the capacitor and keep thedryer running.

There are three dryness levels; MoreDry, Normal Dry and Less Dry. Thesedryness levels have been accomplishedby placing resistors on the electroniccontrol (printed circuit board) androuting the bypass wiring accordingly.The level of resistance in the circuit ,determined by the dryness levelselected, affects the charge-up rate ofthe capacitor and accomplishes thedesired dryness level. As the clothesget dry, the capacitor is able to buildup a charge to a point where the neonbulb fires, thus triggering the gate on aSCR. When this happens, a circuit ismade through the SCR, energizing thecoil in the relay. This takes only a splitsecond and the relay's coil is then heldenergized through a set of contacts inthe relay.

Also, when the coil in the relay is energized, the timer motor is activatedthrough another set of contacts in therelay. The timer advances and openscam number three for the heater andthe dryer begins a timer controlled

CAUTION

cool-down period. The amount of cooldown time will depend upon the cycleselected: Regular - 6 minutes,Permanent-Press - 13 minutes andPermanent-Press with Press Care - 33minutes. NOTE: These times areapproximate. The timer then advancesto where cam number 1A opens, deenergizing the drive motor and thecycle ends.

TROUBLESHOOTING

When the dryer does not go into cooldown and shut off with dry clothes, youneed to know whether you have acontrol problem or a sensor problem.Troubleshooting the electronic controlis made easier if we break the circuitdown into parts. We can separate thetwo parts by disconnecting the W-BUwire in the control panel at the plasticcoupler. The upper part contains theelectronic control assembly which consists of the edgeboard connectorassembly, printed circuit boardassembly and relay. The lower partconsists of the sensor assembly locatedon the tumbler front bulkhead.

Separating the two areas by pulling thewires apart at the coupler will showwhere the problem is located. If thedryer is started without any clothes inthe drum and shuts off in about 20minutes without the sensor circuithooked up, then the sensor must bekeeping the dryer from shutting off.



NOTE: This amount of time is forRegular Fabrics on a Less Dry setting.A setting of Normal Dry or More Drywill add more time before the dryershuts off. If the dryer does not shut off,then the problem is in the electroniccontrol assembly.

Sensor Assembly

1. Disconnect power supply.

2. Remove front panel.

3. Remove wires going to the sensorbars.

4. Check with ohmmeter to make surethere is NO continuity across thesensor bars. If you have continuityacross the sensor bars the capacitorcannot build a charge, it will continually bleed off.

CAUTION

Always disconnect power supplybefore making continuity orresistance checks.

5. Check to make sure the sensor bar(the one not connected to cabinetground) is not shorted to cabinetground. If this sensor bar has aleakage path to cabinet ground, thecapacitor cannot build a cllarge andwill continually bleed off. Useohmmeter to ~heck from sensor barto cabinet ground.

Electronic Control Assembly

If dryer does not go into cool-down andshut off with the sensor disconnectedthe problem is in the electronic controlassembly. While the dryer is running,observe the neon bulb on the electroniccontrol (printed circuit board). Whenthe capacitor reaches approximately 72volts, the neon bulb "fires" (flashes),the SCR conducts, the relay coil isenergized and the contacts in the relayclose.

If neon bulb "FIRES" but timer doesnot advance (timer motor is not energized):

1. Check relay coil for continuity orresistance.

A. Disconnect power supply.

B. Remove BK and BR wires fromrelay (refer to electrical wiringdiagram).

C. Attach meter leads across theseterminals and complete check. Ifchecking resistance, you should seeabout 2200 ohms of resistance. Nocontinuity, replace relay.

2. Check continuity across contactsO-BK to RD in relay. When closed,this set of contacts is used to keepthe coil energized.


B. Remove wires O-BK and RDfrom relay.

CAUTION --------------------------,

Always disconnect po~er supply before making any continuity checks orresistance readings.


C. Remove BK wire from buzzer.

D. Attach motor test cord to the BKwire (removed from buzzer) and tothe O-BK wire (removed from relay).

E. Plug motor test cord into outlet(coil in relay should now be energized).

F. Check for continuity from terminal RD on relay to terminal O-BKon relay. No continuity, replacerelay.

CAUTION SHOULD BE EXERCISEDWHENEVER WORKING AROUNDLIVE VOLTAGE.

3. Check continuity across contactsW-BK to RD in relay. When closed,this set of contacts is used to energize the timer motor by bringing theneutral side of the power supplythrough the relay, to the timermotor.


B. Remove wires W-BK, O-BK andRD from relay.

C. Remove BK wire from buzzer.

D. Attach motor test cord to the BKwire (removed from buzzer) and tothe O-BK wire (removed from relay).

E. Plug motor test cord into outlet(coil in relay should now be energized).

\"-

CAUTION

F. Check for continuity from terminal RD on relay to terminal W-BKon relay. No continuity, replacerelay.

4. Replace electronic control (printedcircuit board).

If neon bulb does not "FIRE":

1. Check capacitor.


B. Remove electronic control(printed circuit board).

C. Set ohmmeter to an ohm scale,such as Rx100.

D. Place meter leads into openingsin the edgeboard connector wherecapacitor leads terminate. First,make sure you have discharged thecapacitor by shorting the leads. Usea piece of insulated wire with theends stripped.

E. Needle should deflect to one sideand then slowly drop back to zero.

F. Failure to deflect the needlewould indicate an open capacitor.Failure of the needle to drop backwould indicate a shorted capacitor.Replace edgeboard connectorassembly.

2. Replace electronic control (printedcircuit board).

MICROPROCESSOR BOARDCONTROL MODELS

The microprocessor board receivesinput information from the various components involved with the operation ofthe dryer; such as the dryness sensorand the thermistor. It uses this information to determine the necessarycontrol for the completion of the cycle.

One of the ways it accomplishes this isthrough the use of control relays. Acontrol relay (S.P.S.T.) is placed in themotor circuit for both the gas and electric dryer. Another relay (S.P.S.T.) isplaced in the heat circuit for the electricdryer only. With these relays themicroprocessor board is capable ofusing a low voltage circuit to control ahigh voltage circuit. We can call thesetwo circuits the control circuit and thecontrolled circuit. NOTE: The controlfor the gas dryer's gas valve circuit isdifferent and is covered later.

The control circuit for the drive motorconsists of the microprocessor boardand the Motor Relay's coil. The controlled circuit for the drive motor consists of the Motor Relay's switchcontacts, thermal fuse and cut-off drive,motor and door switch. The microprocessor board starts the drive motorby sending 24 VDC to the MotorRelay's coil. When energized, the coilcreates a magnetic field that closes the

CAUTION

switch contacts in the relay and provides a path for voltage to the motor.When the microprocessor board determines it needs to stop the motor, itremoves the 24 VDC to the relay's coil.The switch returns to its normally openposition and the path for voltage to themotor is opened.

The control circuit and controlled circuitfor the heating element on the electricdryer operate on the same principle asthe motor relay's circuits. When themicroprocessor board wants to energize the heating element it sends 24VDC to the coil in the Heater Relay anda path for voltage is completed throughthe switch contacts to the heatingelement. When the 24 VDC areremoved from the coil the switch contacts open and the path for voltage tothe heating element is opened.

TROUBLESHOOTING

When trying to determine what iscausing the problem (drive motor willnot run or heating element will notcome on), separate the two circuits toisolate the problem area. Start with thecontrol circuit (it has to function beforethe controlled circuit will work). Determine what is involved in this circuit andproceed to check the components. Ifthese components are found to be functioning correctly, focus on the controlled circuit. Determine what isinvolved and proceed in checking thecomponents.

DRYER (MICROPROCESSORBOARD CONTROL)

A microprocessor board provides thecontrol for this dryer. It accomplishesthis control with several components.The components involved are the transformer, thermistor, control relays,dryness sensor and lint filter switch.

To start the dryer the user selects thedesired program by pressing the indicated pad on the menu. There are 17of these pads from which the user canselect the programs and options for thedryer. Behind the pads are actuators(push rods) that activate switches onthe microprocessor board to initiate theprogram and options. NOTE: Anoption can be selected only after aprogram has been selected.

No test board is available to checkmicroprocessors. Therefore, all othercomponents in this section should bechecked first. If no problem is found,replace microprocessor.

TRANSFORMER

A step-down transformer, consisting ofa primary winding and three secondarywindings, is used to provide the necessary voltages to the microprocessorboard. The primary side of the transformer receives the voltage (120 voltsmeasure across L1 and Neutral). Thetransformer then steps this voltagedown through the secondary windingsinto the voltages needed to power the

microprocessor board and provide thevoltages that the microprocessor boarduses to control or operate the variousfunctions of the dryer. The output voltages on the secondary side are 20.7VAC, 22.6 VAC and 3.8 VAC (thiswinding has a center tap that provides1.9 VAC when measured from thecenter tap to either of the outsideleads).

VARISTOR

The varistor is a semiconductor device(solid state) connected across theprimary input terminals on the transformer. Its function is to protect themicroprocessor board against voltagesurges or spikes. The resistance of thevaristor decreases as the voltageacross it increases. If the voltageexceeds the "threshold" of the varistor,its resistance will decrease rapidly tothe point of providing a short circuitacross the primary terminals. This maytrip circuit breaker or open fuse ordestroy varistor. If varistor isdamaged, replace transformer.

TROUBLESHOOTING

Because the transformer provides thepower to the microprocessor board itshould be checked first if it appears themicroprocessor board or any of thecomponents in its circuitry is not func-

tioning properly. In checking or troubleshooting the transformer it isimportant to remember the transformeronly transforms or changes the voltageto different values. It does not rectifythe voltage to DC, that is done on themicroprocessor board., NOTE: Thereare two sizes of spade terminals usedon the transformer. The two largespade term!nals are used for theprimary winding and the smaller spadeterminals are used for the secondarywindings.

FAULT CODE

The microprocessor board has thecapability to detect certain problemsassociated with the operation of thedryer. When the microprocessor boarddetects one of these problems it displays a fault code in the dryer's displaywindow. The fault code is displayed asa letter F followed by a number thatcorresponds to the problem. Themicroprocessor board makes the dryerinoperative for all but one of the faultcodes. Fault code F-9 is the exception,it does not appear in the display(unless a certain procedure is followed)and does not make the dryer inoperative.

CONTROL PANEL ASSEMBLYCOMPONENTS

TYPES OF CONTROLS

There are four basic types of controlsused to determine the operating time ofMaytag dryers; they are Timer, Automatic Control, Electronic Control andMicroprocessor.

Timer Control

These models utilize an electrical timerwhich the user sets to the number ofminutes recommended in the operatinginstructions or as experience indicatesnecessary.

The timer knob and dial are attached tothe timer shaft. At the other end of theshaft is a cam which controls both thedrying time and the cool-down.

With the timer set at 20 minutes asshown in the drawing the circuit is completed through the timer to the drivemotor and heater circuit.

SECTION 3. SERVICE PROCEDURES 3-1

As the timer advances towards the offposition, the switch arm drops into stepone. This breaks the circuit to theheater. Since the circuit is still made tothe drive motor, the tumbler will continue to rotate and the air will continueto be pulled through the tumblercooling the load before the dryer shutsoff.

When an air fluff selection is made,only the circuit to the drive motor andtimer motor is made.

Auto Dry Models

The length of the cool-down perioddepetlds upon the cycle selection. Permanent Press has an extended cooldown to lower the temperature of thegarments so as to minimize wrinklingwhich would result from the warm garments coming to rest at the bottom ofthe tumbler.

ED/GD401 1090

The auto dry models operate on theprinciple that as long as the load beingdried is damp, and rapid evaporation istaking place, the temperature of thedryer and exhaust air will remain relatively low. It also follows that as theload gives up moisture and the rate ofevaporation slows down, less BTU's orheat is used in evaporation and thetemperature of the load and exhaust air


increases. With this in mind, let's lookat the circuitry.

With the timer set in this position, thecircuits are completed to the heatsource and drive motor.

At the beginning of the cycle the load isdamp, the heat input is used up inevaporation of the moisture and thereis little increase in the air temperature.As the load becomes drier, less heat isused up in evaporation and the temperature of the load and exhaust air startsto rise. The exhaust air is beingpushed over the regulating thermostatand as the temperature of the exhaustair rises so does that of the thermostat.Once the thermostat reaches a temperature of approximately 1400 F the circuitis broken to the heat source and at thesame time is completed to the timermotor.

When the timer is set to a degree ofdryness, the circuit is completed to theheat source and the drive motor. Thedifference between this control and a,standard timer operated dryer is thefact that the timer motor is not initiallyin the circuit. To see how the controlworks, let's assume that the load to bedried is a normal load with the garments of somewhat uniform weight, theauto regular setting is selected and thedial set on the middle mark between"more dry" and "less dry".

As indicated in the timer schematicbelow, the maximum timer controlleddrying time on an auto-dry regularsetting is approximately 31 minutesplus a five"minute cool-down. Since weset the dial to the middle mark we haveset the timer at about the mid point orfor approximately 15 minutes of timeddry.

At this point the unheated air is coolingthe load and the timer motor isadvancing the timer towards the offposition.

In this example, after a total of approximately 13 minutes of heat off time thetimer will have advanced to the pointwhere Cam 2 closes the timer motorswitch which in turn advances the timerout of the heat portion of the cycle andinto the cool-down period.

Each time the thermostat cycles theheat period is shorter and the heat off(timer motor on) time is longer.

will take a relatively long period oftime. By the same token, the moisturecontent and the evaporation rate takingplace during the first heat off periodmakes it shorter than subsequent heatoff periods.

CYCLINGTHERMOSTAT

TO HEATMOTORTO TIMER

As the temperature of the tumbler, theitems being dried and the exhaust airdecrease, so does the temperature ofthe thermostat. When the thermostatcools to a temperature of approximately1250 F. the thermostat returns to itsnormal position breaking the circuit tothe timer motor and again completingthe circuit to the heating element or gasvalve.

A selection of the middle mark is agood starting point. Experience gainedfrom drying a few loads will enable theoperator to pick a point, either more orless dry, which is most pleasing. Oncethis point is determined, it can be usedfor most loads as the automatic control,based upon time and temperature, willautomatically adjust itself to the size ofload.

Note: The temperatures quoted are theoperating temperatures of the thermostat and not the temperature of theclothing or exhaust air. Because of itsmass, the thermostat will heat up andcool down slower than the air temperature.

If the operator is drying a poorly mixedload; bulky items such as cotton socksalong with lightweight flat items itwould be desirable to move the dial tothe "more dry" so that more time isavailable to condition the load or toallow the moisture to surface on thebUlky items. This is not necessary on amore uniform load of either bulky orlightweight items.

THERMOSTATS

THERMOSTATS

There are three different kinds of thermostats in these dryers.

1. Bi-Metal type~

2. Resistance type (Multi-temperature).

3. Thermal Fuse type.

All react essentially to temperature withdirect effect on heat on or heat off functions of a dryer.

To remove those located on blowercover:

1. Remove 2 screws from Front Paneland swing panel out.

2. Remove wires from thermostat.

3. Remove screws securing thermostatto cover.

1600 THERMOSTAT - MicroprocessorModels

Bi-Metal Type

The 160° thermostat functions as a backup to the thermistor. It is mounted onthe blower cover. The thermistor, inconjunction with the microprocessorboar~ and heater relay, is used tocontrol the cycling of the temperaturebetween 135°F and 155°F. The 160°thermostat is placed in series with thegas valve I heating element and willopen the heat circuit in the event thethermistor fails to open the circuit attemperatures above 155°F.

ED/GD401 1090

To remove the 1600 thermostat:



3. Remove the thermostat covermounted to the base (electric dryeronly).

4. Disconnect wires from the thermostat.

5. Remove the two screws securing thethermostat to the blower cover.

To check the 1600 thermostat:

CAUTION ----------,


Check for continuity across thermostatat room temperature. Attach meteracross terminals BK and PU. No continuity, replace.

THERMISTOR - Microprocessor Models

Resistance Type

The thermistor is a semiconductordevice (solid state) that has a negativetemperature coefficient of resistance;its resistance decreases as its temperature increases and vice versa. Thethermistor functions as the "sensingcontrol" for the dryer's heat circuit. No..cycling thermostat is used. It ismounted on the blower cover and is


connected to the microprocessor boardthrough edgeboard connector CC (referto schematic). Mounted on the blowercover puts the thermistor in the air flowof the air being exhausted from thedrum. The increasing or decreasingtemperature of the exhausted airchanges the resistance of thethermistor. The microprocessor boarduses this input information to controlthe heat circuit. On the electric dryerthe microprocessor board controls the24 DC voltage to the heater relay, onthe gas dryer it controls the L1 side ofthe power supply through edgeboardconnector BB (refer to schematic).

To remove thermistor:



3" Remove the thermostat covermounted to the base (electric dryeronly).

4. Remove the two wires, PK-BK andPK-BK, from the thermistor.

5. Remove the two screws that attachthe thermistor to the blower cover.

ED/GD401 1090

Check the thermistor:

1. Remove the two wires on thethermistor, PK-BK and PK-BK.

2. Place ohm meter across these wiresand check resistance of thethermistor. At room temperature,77°F, you should read about 10,000ohms. At 140°F you should readabout 1750 ohms.

Note: Do not check with line voltage(120 VAC), the thermistor is part of thelow voltage circuitry.

THERMAL FUSES

The function of the thermal fuse andthermal cut-off is to stop the dryer inthe event an over heating conditionshould occur. The electric dryer has athermal fuse mounted on the right sideof the heat cone and a thermal cut-offmounted on the blower cover. The gasdryer has a thermal cut-off mounted onthe blower cover. Both are referred toas "thermal fuse" on the electricalschematic. The thermal fuse and cut-offare placed in series with the drivemotor. If one of these should open, thedrive motor will stop and the circuitthrough the centrifugal switch for thegas valve / heating element will alsoopen, breaking the heat circuit. Thethermal fuse and thermal cut-off are notinterchangeable or resettable and mustbe replaced after the over heatingproblem is corrected.

Note: If one of these thermal devicesopens, it indicates something hascaused an unusual amount of heat tobuild up around the device. If thishappens, depending on the model,REPLACE the hi-limit thermostat andcycling thermostat or the hi-limit ther-


mostat and the 160° thermostat andthermistor/microprocessor board combination along with the thermal devicethat failed.

GAS VALVE AND RELATED COMPONENTS

The gas controls utilize a direct ignitionsystem (there is no pilot light). Thethree major components of the gas are:Igniter, Radiant Sensor and Gas Valve.

1. IGNITER -- When the controls callfor heat, line voltage is applied tothe igniter. This causes the igniterto heat up becoming cherry red. Itcan reach a temperature of approximately 2200° F in about 30 seconds.

ED/GD401 1090

Gas contacting igniter at this temperature will ignite immediately.

2. RADIANT SENSOR -- The radiantsensor operates much like a regularthermostat. It is mounted to theside of the combustion cone over anopening which exposes the sensorto the igniter and burner flame.

In its normal condition, the contactsin the radiant sensor are closed andthe circuit is completed to the

igniter. As the igniter heats up, theheat radiated by the igniter causesthe radiant sensor contacts to openbreaking the circuit to the igniter.

3. GAS VALVE -- The gas valve isactually two gas valves, one inseries with the other. This is asafety feature providing added protection against gas released in theevent of a failure of one of thevalves to seat properly.

The first valve is opened byasolenoid which has two separatecoils built into one solenoid. Thissolenoid uses what is termed a splitcoil. The coils are referred to as theholding coil and the booster coil.

BOOSTERCOIL

Both coils are needed to lift thearmature and open the valve. Theholding coil is strong enough to

\

, keep the valve open once the arma-ture has been lifted.

The second of the two valves isoperated by the traditional one coilsolenoid. This is called a secondarycoil.

SECONDARYCOIL

First, note on the wiring diagram thatthe radiant sensor contacts are wiredacross the secondary coil. This effectively bypasses current around the secondary coil when the radiant sensor


contacts are closed. Valve 2 cannotopen with the radiant sensor contactsclosed.

The booster coil and the igniter arealso wired in parallel. Note that whilethese two components are in parallelwith each other, they are wired inseries with the radiant sensor and secondary coil combination. When theradiant sensor contacts are closed, fullline voltage is available to the boostercoil and to the igniter. When theradiant sensor contacts open currenthas to flow through the secondary coilon Valve 2 in order to get to thebooster coil and to the igniter. A significant voltage drop develops across thesecondary coil. While the parallelbooster coil and igniter are still in thecircuit, they become ineffective due tothe greatly reduced voltage available tothem.

Operation: Dryer controls calling forheat.

PHASE I

Power reaches the valve assembly bymeans of the Molex wiring connector.The black valve harness wire isnormally the "hot" side of the line andthe red is normally the neutral side ofthe line and is completed through themotor centrifugal switch.

\Radiant sensor contacts clo~ed.

The holding coil, booster coil andigniter all receive line voltage. Theholding coil and booster coil develop

ED/GD401 1090

the necessary magnetic pull to openValve 1. The igniter, operating at linevoltage, begins to get very hot. Theheat radiated by the igniter affects theelement of the radiant sensor.

IGNITER

Because the secondary coil on Valve 2is bypassed by the radiant sensor contacts, Valve 2 remains closed and prevents the release of gas.

PHASE /I

The igniter is now hot and Valve NO.1is open. With the igniter hot, two thingsoccur:

1. As the igniter is heated, its resistance decreases.

2. The heat from the igniter causes theradiant sensor switch to open.


PHASE 11/

Valve 1 is being held open by theholding coil and with the radiant sensorcontacts open because of the intenseheat from the igniter, the current pathsin the circuit change.

1. With the sensor contacts open, thesecondary coil is no longerbypassed. It is now in series withthe parallel combination of thebooster coil and the igniter.

Because of the very low resistanceof the hot igniter, most of the linevoltage is dropped across the secondary coil. Only a small percentage is dropped across thebooster coil and igniter.

ED/GD401 1090

2. The secondary coil now opens Valve2 releasing gas across the stillextremely hot igniter. The burnerflame is ignited.

While the igniter will cool, the tip ispositioned in the burner flame whichkeeps it hot and the resistance low.

The ignition cycle is now completedand the drying cycle begins.

The gas valve as shipped with the dryeror for repair is set for use with naturalgas, Because of differences in operating pressure and heat content ofother gases, the valve must be converted to use fuels other than naturalgas.

Conversion kits are available to convertfrom natural to L.P.G. and back fromL.P.G. to natural. Check parts catalogfor correct part number.

COIL REPLACEMENT

To replace the coils on this valve, unplug the dryer from the wall receptacle. Fromthe front through the gas valve access door, unplug the wire harness from the gasvalve coils. Notice the holding and booster coils are now molded together and athree-prong connector is used to conoect them. The secondary coil uses a twoprong connector. Once the coils have been unplugged, remove the two screws thatsecure the coil holding bracket. Remove the bracket and lift the coils off. Replacecoils, bracket and wire harness.

Note: The coil positioning tabs and matching holes in the coil holding bracket foreach coil.


IGNITER

The igniter is used to ignite the gas asit comes from the gas valve. It islocated on the left side of the burner(as viewed from the front of the dryer).The igniter is very fragile and must behandled carefully. Should you find anigniter which has shattered, replaceigniter. Operate dryer and see if igniterstays on. If igniter stays on longer than40 seconds, replace radiant sensor.

SECTION 4. PRE-INSTALLATION CONSIDERATIONS

LOCATING DRYER

Dryer should be located as close to the washer as possible, considering availabilityof gas, electricity and location that makes exhausting practical.

For proper operation, it is important to make sure the room where dryer is locatedhas adequate make-up air. This is especially important in any areas such asbedroom, bathroom or closet.

On gas dryers, adequate clearance must be maintained to insure adequate air forcombustion and proper operation of the dryer. The area where the dryer is locatedmust not obstruct the flow of combustion or ventilating air. When locating a Maytagdryer, the following dimensions should be taken into consideration.

When installing the dryer the following minimum clearances to combustibles shallapply: clearance to wall: sides - 0 inches, top - 0 inches with outside exhaust, rear- 0 inches with outside exhaust, 6 inches with inside exhaust.

EXHAUSTING

DO NOT EXHAUST DRYER INTO ANYWALL, CEILING, CRAWL SPACE OR ACONCEALED SPACE OF A BUILDING,VENT CONNECTION, GAS VENT ORCHIMNEY. THIS COULD CREATE AFIRE HAZARD FROM LINT EXPELLEDBY THE DRYER. FOR THE SAMEREASON, WE RECOMMEND ONLYMETAL EXHAUST DUCT TO MINIMIZERESTRICTED AIR FLOW AND RELIABLY INSURE THE CONTAINMENT OFEXHAUST AIR, HEAT AND LINT.NEVER INSTALL A SCREEN OVEREXHAUST OUTLET. NEVER USEPLASTIC OR OTHER COMBUSTIBLEDUCTWORK. FREQUENTLY CHECKAND CLEAN VENT HOOD TO ASSUREPROPER OPERATION.

A clothes dryer produces combustiblelint and the area around the clothesdryer should be kept free of lint. It isrecommended that the dryer beexhausted to the outside using 4" rigidor flexible metal ducting.

When located in a bedroom, bathroomor closet, the dryer must be exhaustedto the outside of the dwelling.

Once location of the exhaust outlet isdetermined, a 4 1/4" hole should be cutin the wall to accept the exhaust hood.To permit sufficient air circulationunder the exhaust hood, there shouldbe no less than a 12" clearancebetween the bottom of the exhausthood'and the ground. When possible,the exhaust hood should not exhaust

ED/GD401 1090

directly into a window well. DO NOTTERMINATE EXHAUST UNDER AHOUSE OR PORCH.

Note: Where the exhaust hood is to beinstalled through masonry, a specialmasonry saw is necessary to cut thehole.

Install the exhaust hood and securewith screws to the outside wall and sealwith caulking compound.

The exhaust hood may also be installedthrough a window by installing awindow plate. Window plates are available. Install as shown.

Install ductwork from the dryer toexhaust hood. All joints must be madeso exhaust end of one pipe is inside theintake end of next pipe. On flexiblemetal ductwork, all joints should besecured with a clamp. DO NOT usesheet metal screws when assemblingrigid ducting. These should be taped.

SECTION 4. PRE-INSTALLATION CONSIDERATIONS 4-2

FLEXIBLE DUCTWORK L1MITA TlONS

Flexible metal ductwork should notexceed 34' of straight 4" ducting. Theexhaust hood is equivalent to 8' of ductand each 90 degree bend is equivalentto 8'. As an example, if an exhausthood is used and two 90 degree bends,the maximum straight run would be 10'.

Note: If the radius of a bend with 4"duct is 12" or greater, the bend can beconsidered a straight run. No morethan three 90 degree bends should beused in any run with an exhaust hood.

RIGID DUCTWORK LIMITATIONS

Rigid metal ductwork should notexceed 50' of straiglit 4" duct. Each 90degree elbow and the exhaust hoodshould be considered equivalent to 8''a{ straight ductwork. For example, if anexhaust hood and two 90 degreeelbows are used, the maximum straightduct allowed would be 26'. Not morethan three 90 degree elbows should beused in any rigid ductwork run with anexhaust hood. Four feet of straight

ED/GD401 1090

duct should be allowed between 90degree elbows.

GUIDE FOR PROPER EXHAUSTING

1. Keep the duct as short as possible.The longer the duct the more frictionand resistance to air flow.

2. Keep the number of elbows and thedegree of bend to a minimum tominimize air resistance due todynamics. We recommend that notover 3 elbows be installed in theduct.

3. The smoother the inside sUrfa~e ofthe duct, the less the friction and thegreater the air flow. It is because ofthis that we recommend usingsmooth rigid aluminum ductwork.Flexible ductwork has a spiralwashboard surface which increasesfriction and sets up dynamic turbulence which decreases air flow.

4. Never reduce the area of the duct.A 4" round duct has an area ofapproximately 12.57 square inches.The area of the duct should neverbe reduced below this figure.

5. Dryers should be exhausted to theoutside of the building.

6. Do not exhaust dryer into any wall,ceiling, crawl space, a concealedspace of a bUilding, vent connection,gas vent or chimney. A lint accumulation in such an area creates a firehazard.

7. When located in a bedroom,bathroom or closet, the dryer mustbe exhausted to the outside of thedwetring.

8. Do not install vent hood at groundlevel. There should be a 12"(30.5cm) clearance between the


bottom of the exhaust hood and theground.

9. All exhaust duct joints should betaped to prevent lint and moistureladen air from being expelled intothe building.

10. The exhaust duct and vent hoodshould be checked periodically andcleaned as necessary to prevent alint build-up.

NOTE No.2

The figures for flexible duct apply onlyto the flexible metal duct. For othertypes of flexible ducts, refer to manufacturer's design data concerning airfriction loss. Friction 1055 in inches ofwater, as measured by a manometer,should never exceed .58" of watercolumn.


LEFT SIDE OR BASE EXHAUST

If dryer is to be exhausted out the leftside or through base, use the accessory 304652 exhaust kit, instructionsare included with the kit.

oNonexhausted Installations

Always exhaust gas dryers to theoutside.

NOTE -------------,

IN CANADA, ALL DRYERS MUST BEEXHAUSTED TO THE OUTSIDE.

If the installer has determined that anonexhausted installation will be made,a 303736 exhaust deflector should beIn,stalled. Maintain a 6/1 clearancebetween the back of the control paneland the wall.

Note: A dacron mesh lint bag, Part No.3011353, is available for use on nonex-

ED/GD401 1090

hausted installations. Although the lintscreen and the lint bag will retain mostof the lint expelled, a certain amount ofline will be expelled into the laundryarea. AN ACCUMULATION OF LINTCREATES A FIRE HAZARD. THEREFORE, FREQUENT CLEANING OR VACUUMING OF THE LINT ACCUMULATIONIS NECESSARY.

ADDITIONAL FACTS ABOUTEXHAUSTING

These large capacity Maytag dryers aredesigned to move 180 cubic feet of airper minute. As exhaust ducting isadded, it imposes resistance to the flowof air which must be overcome by thedryer exhaust fan. This resistance isdue to static, velocity and dynamicpressure which is expressed in inchesof water column as measured by amanometer.

There are two types of pressure losses:

1. Static or friction losses and

2. Velocity or dynamic losses.

Static or friction losses. (We will referto this as friction.)

Friction losses are caused by the actualrubbing of the air molecules along thesides of the duct. Pressure losses instraight runs of duct are referred to asfriction losses. The pressure woulddrop due to friction losses betweenpoints 1 and 2 of the duct in the following drawing.


~_3 _

------_/

Dynamic losses result from air turbulence which occur when the air flowchanges direction or when there is achange in the cross-section area of theduct.

1. A change of cross-sectional area i5illustrated in the above drawing.The reducer deceases the crosssectional area which increases thevelocity and results in dynamicpressure loss. The amount of friction through a reducer variesdirectly with the square of thevelocity of air. This simply meansthat the resistance through areducer is very high as compared toa straight run of duct.

Proper operation and efficientdrying is dependent upon proper airflow. The dryer is designed for useof a 4" duct and reductions in theduct are not recommended.

2..Dynamics\

Between 2 and 3 in the drawing, areducer has been added to the duct.

ED/GD401 1090

The reducer opposes the air flow·and sets up air turbulence whichresults in a pressure loss.

There are many factors influencingair flow such as the considerationslisted under Guide for ProperExhausting. In addition to theseitems, the operator's practices alsoaffect air flow, efficiency and theresulting drying times.

A. Failure to clean the lint filterregularly will result in a reduction inair flow and will cause the dryer totake longer to dry the clothes.

B. Overloading restricts proper airflow through the drum which willalso decrease efficiency and extendthe dry time.

ADJUSTING MAIN BURNER

To adjust main burner flame, loosenscrew holding air shutter and rotateshutter until a yellow flame appears.Then reverse the rotation of the shutteruntil the yellow disappears and theburner has a steady blue flame. Toachieve this, it may be necessary toadjust the flame until only a very smallyellow flame is at the tip of the blueflame. After a period of about fiveminutes, all of the yellow should disappear. If not, readjust the shutterslightly. When the desired results areachieved, tighten the screw to lock theshutter in place.

SECTION 4. PRE-INSTALLATION CONSIDERATiONS 4-6

Additionally, a 1/8" N.P.T. (Natural PipeThread) plugged tapping, accessible fortest gage connection, must be installedimmediately upstream of the gas supplyconnection to the dryer. Refer to yourlocal gas utility or plumbing contractorshould you have questions on theinstallation of the plugged tapping.

GAS CONNECTION

AGA Recommends:

DRYER

1/8" NPTPLUG

Gas operated dryers are equipped witha burner orifice for operation onNATURAL gas. If the dryer is to beoperated on LP gas, it must be converted correctly for safety and properperformance. Conversion kits fromNATURAL to LPG, or LPG to NATURALare available. If other conversions arerequired, check with local gas utility forspecific information concerning conversion requirements.

NOTE -----------,

The conversion should always beperformed by a qualified servicetechnician.

\'.

A 1/2" gas supply line is recommendedand must be reduced to connect to the3/8" gas line on the dryer.

ED/GD401 1090

The dryer and its individual shutoffvalve must be disconnected from thegas supply piping system during anypressure testing of the system at testpressures in excess of 1/2 P.S.I.G.

In other words, if the test pressure isabove 1/2 P.S.I.G., disconnect pipe fordryer before testing pipe. If it is lessthan 1/2 P.S.I.G. it's ok to leave connected but shut off internal shut-offvalve in dryer.

The gas supply should be connected tothe dryer uSing pipe joint compound ora Teflon@ tape on male thread connections.

Note: Any pipe joint compound usedmust be resistant to the action of anyliquified petroleum gas.

Turn on gas supply and open theshutoff at the gas valve. Check all gas


connections for leaks using a soap solution. If bubbles occur, tighten connections and recheck. DO NOT use anopen flame to check for gas leaks.

Note: As a courtesy, many local gasutilities will inspect a gas applianceinstallation. Check with your utility tosee if this service is provided in yourarea.
