This defrost thermostat is an essential component that prevents frost buildup by controlling when the defrost heater activates and deactivates. When the evaporator temperature drops to 22°F, the thermostat closes to allow the defrost heater to operate. Once the temperature rises to 45°F, it opens to end the defrost cycle and resume normal cooling.
