DEFROST HEATER
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.
How To Remove The Defrost Heater
1. Disconnect refrigerator from electrical supply.
2. Remove freezer section bottom shelves and baskets.
3. Remove ice container and rail assembly.
Multiconnector at back of rail assembly must be
disconnected before rail assembly will come free.
4. Loosen two screws holding ice maker to right side
of compartment, just enough to lift ice maker free.
Multiconnector must be disconnected before ice
maker will come free from compartment.
5. Remove two rail assembly supports. (two screws per
support).
6. Remove four screws from evaporator cover.
7. Remove five screws on evaporator air duct cover.
8. Disconnect two leads to defrost heater.
NOTE :This is a good time to test the heater. Check
resistance of defrost heater using a multimeter.
Resistance should be very close to 30 ohms.
Replace defrost heater if resistance readings are
out of range.
9. Unclip ground wire hooked to drain trough.
10.Remove screw holding evaporator bracket (through
drain trough) to cabinet.
11.Remove rivet (must be drilled out) holding evaporator
bracket to drain trough.
