A defrost thermostat is a device that limits how much heat is applied to the defrost heaters typically found in refrigeration units. They allow current to flow when they reach a certain low (cut-in) temperature. During the defrost cycle, they in-turn pass current to the defrost heaters. When the heaters cause the evaporator coils to reach a certain (cut-off) temperature, the defrost thermostat cuts-out and stops the current flow to the defrost heaters. This action protects the refrigerator and the consumer from hazardous conditions and unnecessary power usage. Defrost thermostats fail often due to the large temperature swings that they are subject to.
