This defrost thermostat with attached wiring harness monitors the evaporator coil temperature and signals the defrost heater to turn on or off during the defrost cycle. It is typically mounted on or near the evaporator coils inside the freezer compartment. Replace this part if the refrigerator is not cooling properly, frost is building up excessively on the evaporator coils, or the defrost cycle is not functioning correctly.
