How to Replace the Compressor Start Relay in a Top-Freezer Refrigerator

 

file

This refrigerator repair guide explains how to replace the start relay in a top-freezer refrigerator. The compressor won't run if the start relay fails. The relay sends current to the motor start windings to boost motor torque to start the motor, and to the motor run windings. Once the motor starts, the relay continues to send current to the run windings, but cuts off current to the start windings. A defective start relay won't send current to the start windings, run windings or both.

The start relay includes an overload component that shuts off all current to the motor if the motor overheats. A defective overload trips when the motor isn't overheated, preventing the motor from starting. Replace the defective compressor start relay with the manufacturer-approved replacement part.

Use this repair procedure to replace the compressor start relay in Kenmore, Frigidaire, Electrolux, Whirlpool, KitchenAid, Maytag, Amana, GE, Samsung, LG, Gibson, Crosley, Bosch and Haier refrigerators.
