Description:
<p>The Defrost Timer is a genuine OEM replacement part, compatible with GE brand refrigerators. It controls the amount of time that the refrigerator spends in its cooling and defrost cycles. During the cooling cycle, the compressor runs and cools down the interior of the fridge. During the defrost cycle, however, the compressor shuts off and a heating element turns on. This melts any frost that has built up on the evaporator coils. The timer ensures that both of these cycles occur at regular intervals so that your refrigerator remains efficient and free from frost buildup.</p>
