Dehumidifier Compressors

The compressor start relay attaches to the compressor in your refrigerator. If your refrigerator will not start, one of the most common parts to fail is the compressor start relay. Sometimes called the controller, this device is used to boost the compressor until the unit is running. Other common symptoms connected to start relays include: refrigerator will not start, will not cool, is making a clicking, humming or buzzing sound, or the compressor itself is warm to the touch. You may also smell a burnt plastic odor if the relay has failed. Shake the relay and listen for any rattling, as this is a sign that it is faulty.

Overload is sold separately. The start relay briefly boosts the compressor, and then shuts off as soon as the motor gets up to speed.
