New Features

Ice room cooling fan is now in the auger motor housing instead of the freezer

New FeaturesThere is no longer an ice full detector arm that comes down from the ice maker. Instead there is an infrared transmitter and receiver system that detects the level of ice in the bucket. The I/R transmitter is in the auger motor housing and the receiver is in the ice maker itself.

I/R Receiver (ice maker)

New FeaturesNew left side refrigerator door vertical hinged section

The vertical hinge attached to the left side door of the refrigerator has a moveable, spring loaded, latch at the top of it that allows the door to be closed even if the hinge is in the wrong position

New FeaturesThe ambient and humidity sensors as well as the dispenser lock out switch are now located on top of the left side refrigerator door instead of under the hinge plate. This eliminates the need for extra wiring connectors in the event the door needs to be removed.

Refrigerator Ice Maker Removal

LatchWhile pressing the latch on the top right side of the ice bucket, lift up the bucket and pull it out

Refrigerator Ice Maker Removal

Once the ice bucket is removed there is a caution that must be observed before attempting to remove the direct cooling ice maker.

Refrigerator Ice Maker Removal

To enter the forced mode, press and hold these 2 buttons on the display panel until the display blanks out. Then press any button until “Fd” appears on the display. This indicates the freezer section as well as the refrigerator section is in the defrost mode.

Refrigerator Ice Maker RemovalWhile in the forced defrost mode for both refrigerator and freezer compartments, “Fd”, start disassembling the I/M. Remove the screw from the wire housing cover and remove the cover.With the power disconnected, unplug the I/M connector.

Refrigerator Ice Maker Removal

Using a flat blade screw driver, pry the latch on the left side of the lower I/M tray to release the tray. Once released CAREFULLY pull the tray down. It will not come out as the rear of the tray is attached to the I/M.

Refrigerator Ice Maker Removal

If the I/M was not allowed enough time to defrost ice build up, the lower tray and/or the cooling tube can be damaged.

Refrigerator Ice Maker Removal

CAREFULLY insert a flat blade screwdriver between the cooling tube and the mold of the I/M and pull the tube down

Refrigerator Ice Maker RemovalWhile pressing the latch on the I/M, pull out and down to remove the Ice Maker.

※ When removing the I/M, be sure that the cooling tube grommets (6ea) are not removed and the tube is not damaged.

With the auger motor removed, take out the screws that holds the drain in place and move the drain and Styrofoam insulation away.

Auger Motor Fan Removal

With the Styrofoam insulation removed both the ice maker drain with heater and the fan can now be removed for replacement. Both components are using connectors that unplug.

Non Replaceable Auger Motor Components

If any of these components in the auger motor assembly fail, the entire assembly should be replaced:

•Auger motor•Solenoid•Ice room temperature sensor•I/R transmitter

The fan and drain heater can be replaced with minimal disassembly.

Detecting the I/R Transmitter

The ice bucket level I/R transmitter, located in the auger motor assembly, will not throw an error if it fails. To detect if it is working, view the I/R LED through any camera or most any phone that has a camera and you will see it lit.
