1. Precaution

1. Precaution
Follow these special safety precautions . Although the microwave oven is completely safe during ordinary use, repair work can be extremely hazardous due to possible exposure to microwave radiation, as well as potentially lethal high voltages and currents .
1-1 Safety precautions ( )1. All repairs should be done in accordance with the
procedures described in this manual . This product complies with Federal Performance Standard 21 CFR
2. Microwave emission check should be performed to prior to servicing if the oven is operative .
3. If the oven operates with the door open :Instruct the user not to operate the oven and contact the manufacturer and the center for devices and radiological health immediately .
4. Notify the Central Service Center if the microwave leakage exceeds 5 mW/cm2 .
5. Check all grounds .6. Do not power the MWO from a “2-prong” AC cord .
Be sure that all of the built-in protective devices are replaced . Restore any missing protective shields .
7. When reinstalling the chassis and its assemblies, be sure to restore all protective devices, including: nonmetallic control knobs and compartment covers .
8. Make sure that there are no cabinet openings through which people --particularly children--might insert objects and contact dangerous voltages . Examples: Lamp hole,ventilation slots .
9. Inform the manufacturer of any oven foundto have emission in excess of 5 mW/cm2 ,Make repairs to bring the unit into compliance at no cost to owner and try to determine cause . Instruct owner not to use oven until it has been brought into compliance .
CENTRAL SERVICE CENTER10. Service technicians should remove their watches
while repairing an MWO .11. To avoid any possible radiation hazard,replace parts
in accordance with the wiring diagram . Also, use only the exact replacements for the following parts: Primary and secondary interlock switches, interlock monitor switch .
12. If the fuse is blown by the Interlock Monitor Switch: Replace all of the following at the same time: Primary, door sensing switch and power relay, as well as the Interlock Monitor Switch . The correct adjustment of these switches is described elsewhere in this manual . Make sure that the fuse has the correct rating for the particular model being repaired .
13. Design Alteration Warning: Use exact replacement parts only, i.e.,only those that are specified in thedrawings and parts lists of this manual . This is especially important for the Interlock switches, described above . Never alter or add to the mechanical or electrical design of the MWO . Any design changes or additions will void the manufacturer’s warranty . Always unplug the unit’s AC power cord from the AC power source before attempting to remove or reinstall any component or assembly .
14. Never defeat any of the B+ voltage interlocks . Do not apply AC power to the unit (or any of its assemblies) unless all solid-state heat sinks are correctly installed .
15. Some semiconductor (“solid state”) devices are easily damaged by static electricity . Such components are called Electrostatically Sensitive Devices (ESDs) . Examples include integrated circuits and field-effect transistors. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground .
16. Always connect a test instrument’s ground lead to the instrument chassis ground before connecting the positive lead; always remove the instrument’s ground lead last .
17. When checking the continuity of the witches or transformer, always make sure that the power is OFF, and one of the lead wires is disconnected .
18. Components that are critical for safety are indicated in the circuit diagram by shading, or .
19. Use replacement components that have the same ratings, especially for flame resistance and dielectric strength specifications. A replacement part that does not have the same safety characteristics as the original might create shock, fire or other hazards.
NOTE : Connect the oven to a 20A . When connecting the oven to a 15A,make sure that circuit breaker can operate .

1. Precaution
1-2 Special High Voltage Precautions
1. High Voltage Warning Do not attempt to measure any of the high voltages --this includes the filament voltage of the magnetron . High voltage is present during any cook cycle . Before touching any components or wiring, always unplug the oven and discharge the high voltage capacitor (See Figure 1-1)
2. The high-voltage capacitor remains charged about 30 seconds after disconnection . Short the negative terminal of the high-voltage capacitor to to the oven chassis . (Use a screwdriver .)
3. High voltage is maintained within specified limits by close-tolerance, safety-related components and adjustments . If the high voltage exceeds the specified limits, check each of the special components .
H . V . Diode
Short
H . V . Capacitor
PRECAUTIONThere exists HIGH VOLTAGE ELECTRICITY with high current capabilities in the circuits of the HIGH VOLTAGE TRANSFORMER secondary and filament terminals. It is extremely dangerous to work on or near these circuits with the oven energized . DO NOT measure the voltage in the high voltage circuit including filament voltage of magnetron.
PRECAUTIONServicemen should remove their watches whenever working close to or replacing the magnetron .
PRECAUTIONNever touch any circuit wiring with your hand nor with uninsulated tool during operation .

Timer starts countdown but no microwave oscillation .(No heat while oven lamp and fan motor turn on.)
Fuse is OKOpen or loose lead wire harness
Open thermal cutout (Magnetron)
Open low voltage transformer
Check fan motor when thermal cutout is defective.
Check Ass’y PCB when L.V.T is defective.
Check adjustment of primary, interlock monitor, power relay, door sensing switch.
NOTE 1: All of these switches must be replaced at the same time. (refer to adjustment instructions) Check continuity of power relay contacts and if it has continuity, replace power relay also.
NOTE: Large contact resistance will bring lower magnetron filament voltage and cause magnetron to lower output and/or intermittent oscillation.
NOTE 2: When H.V.Transformer is replaced, check diode and magnetron also.
