Fresh Food Evaporator Assembly

The fresh food evaporator assembly consists of an
evaporator, defrost and drain heaters, bimetal defrost
safety thermostat, thermistor, and evaporator fan
assembly.

All components are housed together and installed in the
refrigerator interior in a recessed compartmet in the
refrigerator ceiling. This compartment extends vertically
into the machine compartment.

To access the fresh food evaporator assembly:

1. Remove the fresh food grille cover by inserting a fl at-
   blade screwdriver into the slot (see photo) and lifting
   up.

2. Remove 4 Phillips-head screws from the fresh food air
    duct cover. Pull the front of the cover down.
3. Disconnect the thermistor and lighting connector.
   Remove the fresh food air duct cover.

4. Remove the 4 Phillips-head screws that hold the

    refrigerator suction line drain assembly in place.
    Remove the assembly.

5. Remove the 2 Phillips-head screws that hold the fresh
    food upper duct cover assembly in place. Remove the
    upper duct cover.

6. Disconnect the remaining electrical connectors.
