why does my kenmore refrigerator freeze up
The temperature control thermostat directs voltage to the compressor, evaporator fan motor, and condenser fan motor (if applicable). If the temperature control thermostat is not working properly, it may cause the refrigerant system to run longer than necessary. As a result, the refrigerator will be too cold. To determine if the thermostat is defective, rotate the thermostat from the lowest setting to the highest setting and listen for a click.
If the thermostat clicks, it is not likely defective. If the thermostat does not click, use a multimeter to test the thermostat for continuity. If the temperature control thermostat does not have continuity at any setting, replace it.
The door gasket prevents air from leaking into or out of the freezer. If the door gasket is torn or not creating a reliable seal, or if the freezer is not shut tightly, humid air can leak into the freezer.
When this humid air passes over the cold evaporator coils, it condenses and freezes on the coils. If humid air is continually leaking into the freezer, the evaporator coils ice over too quickly, and the defrost cycle isnвt able to keep up. To determine if the gasket is creating a reliable seal, close the freezer door on a dollar bill and try to pull the dollar bill out of the freezer door.
If the dollar bill sticks in place, the gasket is creating a good seal. If the dollar bill slides out or falls out, the gasket has a leak. Repeat this procedure all the way around the refrigerator door. If, at any point, the dollar bill does not stick, the gasket is defective. If the door gasket is defective, replace it.
