How does a refrigerator relay work?

The overload relay is a protection device used in the compressor circuit on your refrigerator. Power is applied to the compressor motor windings through the overload device, and the relay is used to add the start winding in the circuit until the compressor is at running speed.

How do you know if your refrigerator relay is bad?

The Shake and Rattle Test Unplug the start relay from the compressor and give it a shake. If you can hear rattling on the inside of the start relay, then the part is bad and will have to be replaced. If it’s not rattling and appears to be in good condition, you may have a problem with the actual compressor.

Can you bypass refrigerator relay?

Use a flathead screwdriver to press down on the space between the relay and its casing. Then, press on the relay itself and pull it out to remove it from the refrigerator. Using electrical tape, connect both ends of the wire back to the relay housing so it completely bypasses the missing relay and closes the circuit.

What causes a refrigerator relay to go bad?

Electrical Surge Refrigerator relays protect the fridge from electrical damage. An electrical surge can be one reason that a relay will fail and overload. When the resistance of the wire impedes the electrical current, the wires can become hot and begin to melt. An electrical surge can cause this to occur.

What causes a refrigerator start relay to go bad?

Can you bypass a compressor start relay?

Relay is an electrical switch that tells your compressor to turn on or off depending on the temperature inside the unit. If the relay stops working, the compressor will also stop. The only solution to pull you out from this miserly is the bypass of the relay system.

It will be located inside the control box, which is usually found attached to the top or side of the fridge. Look on the control board for signs of arcing, burnt connections, damaged foil, wear, or any other damage.

Can a wire wound refrigerator start relay be replaced?

Newer units are solid state relays that require special equipment for checking. These relays easily get fried, unlike the wire-wound relay. If the relay has terminals that are badly corroded, it may need to be replaced. However, some relays just need to be cleaned in order to work again.
