J. Removal and Replacement of Fan Motors

1. Cabinet Fan Motor

Be careful when handling the evaporator shroud assembly. This assembly
includes a defrost heater sheathed in a glass tube. This sheathing can be
easily damaged and may also cause cuts if broken. Heater will also be hot after
a defrost. Use gloves when handling and avoid touching the glass directly. Also
prevent heaters from touching other parts.
1) Remove the refrigeration system cartridge. Perform steps 1 through 16 in "IV.B.2.
Pump‑Down Procedure." Once the refrigeration system cartridge is out, return to
step 2.
2) Disconnect the wires to the fan motor, then remove the defrost thermistor, cabinet
thermistor, defrost thermostat, and defrost heater from the evaporator shroud.
3) Remove the evaporator shroud from the evaporator.
4) Remove the fan motor. See Fig. 9.
5) Install the new fan motor.
Note: Confirm that the fan motor wires are sealed with food grade silicone at the motor
housing.
6) Replace the evaporator shroud in its proper position.
7) Replace the removed parts in their correct positions, and connect the fan motor wires.
8) Once the repair is complete, return to step 17 in "IV.B.2. Pump‑Down Procedure" for
refrigeration system cartridge replacement.
