Fridge Defrost Thermostat Controller ELTH-003 18056 has a unique dual contact assembly excellent for AC or DC applications. The narrow differential of 10°C deg. or less in a low-temperature application makes it an ideal controller for maintaining a constant temperature without a wide temperature swing. This thermostat offers increased sensitivity in an electrically insulated housing.

WHAT does defrost thermostat do?
Temperature – the defrost thermostat measures the temperature of the evaporator, activating once it reaches a set point to warm and defrost the evaporator. Frost thickness – an infrared sensor is used to measure how much frost built up and activate the heating element once it reaches a certain thickness.
