Refrigerator Defrost Timers

Defrost timers in refrigerators are mechanisms that control the level of heating or cooling in a freezer to prevent the build-up of frost. Older refrigerators have timers that run consistently but newer models have timers that are only active during a defrost setting or during compression. Malfunctioning defrost timers can result in frost build-up or improper refrigeration. Like other timers in appliances, these parts are powered by a small motor. They are also often connected to the defrost heater and termination thermostat of the refrigerator. Refrigerator defrost timers can be located behind a freezer's front grill or cover plate, near the compressor, or in the temperature control console.

Common Types of Refrigerator Defrost Timers

Most defrost timers are mechanical and made from metal and/or plastic. The appropriate type of refrigerator defrost timer for any fridge will depend on the make and model of the unit.
