How do you replace the defrost termination thermostat on a Kenmore Refrigerator?

Answer 1

It depends on the model. Some don't have a defrost heater at all, only a timer. On models with a heater, it's either mounted to the evaporator, or actually woven into the evaporator.

You'll need to gain access to the evaporator coils - they're typically at the back of the freezer covered by a panel of some sort. If it's mounted to the coils, then you may be able to replace it yourself.

Also, the heaters rarely go bad - check the defrost termination thermostat as well. If it's near freezing, it should be closed (allowing power to flow to the heater). If it's above freezing, it should be open (cutting power to the heater).

Answer 2

First make sure you unplug refrigerator from the wall outlet. then you will have to expose the evaporator coil, which is normally located behind the back wall of the freezer in a side by side, or freezer top or bottom model, it can also be located in the floor of the freezer in a freezer top model, or the floor of the refrigerator in a freezer bottom model. Once you have exposed the evaporator, look for a small device with two wires leading from it. this device will have the overall shape of a stack of about 12 quarters. this will, in most cases, be located on the aluminum evaporator coil, near where the evaporator is connected to the copper line coming from the back wall/floor. This device clips onto the evaporator with a spring clip, and can easily be removed with your fingers. cut and strip the two wires as close to the present bimetal thermostat, strip the ends of the new thermostat, and connect the two pairs together, it matters not which connects to which, for its an A/C circuit. secure with wire nuts and electrical tape, clip it in the SAME spot as original, replace the back wall/floor. Plug back in, and you will be cooling in no time.
