2. Remove the freezer door.
3. Remove freezer section baskets.
4. Remove screws from fan motor cover and lift out of
evaporator cover.
5. Remove screws from evaporator cover and remove

6. Disconnect wire leads at Molex™ connectors.
(See
Figure 6-49)
7. Remove faulty thermostat from copper tubing.
Defrost Heater For Evaporator Removal
The defrost heater is a radiant “U” shaped resistance
heater, rated at 450 watts. The defrost heater is
energized during that period of the cycle when the
defrost thermostat contacts are closed. The length of
time the heater is energized depends on the amount of
frost accumulation on the evaporator.
To remove the defrost heater:
1. Disconnect refrigerator from electrical supply.
2. Remove the freezer door.
3. Remove freezer section baskets.
4. Remove screws from fan motor cover and lift out of
evaporator cover.
5. Remove screws from evaporator cover and remove
from freezer.
6. Disconnect two leads to defrost heater.
(See Figure 6-50)
7. Unclip ground wire hooked to drain trough.
8. Remove screw holding evaporator bracket through
drain trough to cabinet.
9. Remove rivet holding bracket to trough and set
bracket aside for reuse.
10. Remove screw holding drain trough to cabinet.
11. Lift up and pull evaporator and drain trough out at
bottom. Use caution not to damage suction line or
cap tube.
12. Slide drain trough off evaporator.
13. Remove retainer clamp from bottom of evaporator
that holds heater in place.
14. Grab heater from bottom and pull free of evaporator.
The heater fits very tight to the evaporator, and will
require some force to remove.
15. Replace with new defrost heater.
16. Re-assemble in reverse order.
