DEFROST THERMOSTAT

The defrost thermostat is a temperature sensing device.

Wired in series with the defrost timer and the evaporator

defrost heater, it senses the rise in evaporator

temperature during a defrost cycle and cycles the

defrost heater off after all frost is melted. It is calibrated

to permit a defrost cycle only when the temperature is

below a preset temperature. The contacts in the defrost

thermostat are set to open at 47°F and close at 25°F.

To Test Defrost Thermostat

1. Measure resistance across two thermostat leads at

connector plug. At room temperature, resistance

should be infinity. The contacts are open.

2. Place a couple ice cubes on sides of thermostat.

After a few seconds, thermostat should reset.

3. Measure resistance again. This time, reading

should be 0. Contacts have closed.

4. If you get resistence readings that differ from the

readings in this procedure, replace defrost

thermostat. Contacts are probably burnt.

To Remove Defrost Thermostat

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. Cut two leads coming from thermostat close to base.

You must leave enough wire coming from connector

to allow for splicing new thermostat.

9. Remove faulty thermostat.

NOTE

: The Defrost Thermostat Replacement Kit

comes with a new thermostat, two solderless

connectors and two pieces of heat shrink to allow for

splicing the new thermostat to the connector plug.

10.Crimp two solderless connectors to two leads on new

thermostat.

11.Slip two pieces of heat shrink onto two leads coming

from connector plug.

12.Crimp two solderless connectors to two leads coming

from connector plug.

13.Slip heat shrink over solderless connectors and heat

that area with heat gun until heat shrink is tight around

solderless connectors.

14.Hook thermostat back on evaporator near or at same

place it was before.

15. Reverse Steps 1 - 7 to complete repairs.

NOTE

: An experienced serviceman may choose

not to remove the Ice Maker, bucket and rail

assembly when removing the evaporator, defrost

thermostat or defrost heater. Through experience,

he has learned that only the bottom two screws on

the air duct cover need to be removed once the

evaporator cover has been removed. This allows

the air duct cover to be pulled forward enough to

slide the drain trough out enough to remove the

evaporator.
