How To Test the Compressor Motor

The compressor uses mechanical force to compress the refrigerant gas into a high pressure state. As the gas passes through the coils it dissipates heat and then passes through an expansion valve in the freezer. The gases changes to a low pressure state and consequently drops in temperature. Inside the freezer the fan moves air over the cool coils whcih absorb heat and carry it back out of the freezer. The compressor is accessed from the lower rear of the refrigerator. The compressor is labeled "A", the terminal box is located at the position labeled "B".

The compressor motor can be accessed by removing the terminal cover box. The cover is held on by tension or with a retaining clip.

Caution: Please read our safety information before attempting any testing or repairs.

Before testing the compressor motor, unplug the refrigerator to avoid an electrical shock hazard. Also, if the compressor uses a capacitor, it may contain a lethal electric charge. Do not touch the terminals until you have discharged the capacitor.
