Removing the Evaporator Fan Motor
The evaporator fan motor is mounted on a bracket that is
attached to a shroud mounted to the back wall of the
freezer section. (Fig. 18)
1. Removing the two (2) hex-head screws that secure
the fan motor bracket to the shroud.
2. Disconnect the wiring harness connectors from the
evaporator fan motor terminals.
Servicing the Evaporator, Defrost Bi-Metal and Defrost Heater
The evaporator, defrost bi-metal (Fig. 19) and defrost heater (Fig. 20) are servicable parts on these
units.
Removing the Defrost Bi-Metal
1. Disconnect the wiring harness connectors from the defrost bi-metal leads.
2. Slide the bi-metal mounting clip from the inlet tubing of the evaporator.
Removing the Defrost Heater Element
1. Disconnect the wiring harness connectors from the defrost heater element leads.
2. Carefully unsnap the evaporator tubing from the four (4) plastic clips that secure the evaporator
to the heat shield at the back of the freezer compartment and remove the styrofoam blocks on
both sides of the evaporator. Do not break these blocks. They will need to be reinstalled
when replacing the evaporator in the freezer section.
3. Tip the bottom of the evaporator up and, with a pair of needlenose pliers, remove the clips that
secure the heater element to the bottom of the evaporator. This will free the heater element
from the evaporator.
