Freezer Temperature Control Defrost Bi-metal Thermostat

PL002 03286 Temperature Control Switch Bi-Metal Defrost Thermostat
The function of the defrost bi-metal thermostat is to clip onto the evaporator and protect your evaporator from overheating during the defrost cycle. If your refrigerator does not defrost properly you can test both the thermostat and the heater to figure out which part is at fault. For this repair, you will need a Phillips screwdriver, a 1/4 inch nut driver, a flat blade screwdriver, a pair of wire strippers, a roll of electrical tape, and a few butt splice connectors.

APPLICATION-SCENARIO


How do I know if my refrigerator defrost is bad?

Remove the freezer interior panels that cover the cooling coils. A defrost problem is confirmed if the cooling coils are covered with ice. If there is no ice then the defrost system is working normally and you must look elsewhere for the source of your refrigerator malfunction.
