How to Replace a Refrigerator's Compressor Motor

The main purpose of the compressor motor in a refrigerator is to circulate the coolant of the refrigerator all through the length and breadth of the refrigerator. The compressor also plays an important role behind other functions like instant ice formation or the frost-free feature.

The refrigerator is one of the most common and widely used electronic gadgets, which can be found in every household. A refrigerator runs continuously for almost 24 hours in a day and keeps the food healthy. Generally normal refrigerators are not very expensive, but on rare occasions when they break down, it can cost a lot to repair them. Here we shall give you a brief overview about the working mechanism of the refrigerator and explain in details the steps which needs to be followed in order to replace the compressor motor of a refrigerator.

Before you start any repair work on the refrigerator it is necessary to test the refrigerator relay’s condition and decide whether it needs a repair work to be done. This can be done with the help of a multi tester. If the multi tester fails to give accurate result after being plugged to the “S” and “L” terminal of the compressor, then you can be sure that your compressor motor needs a replacement.

Unplug the Unit from the Main Power Point

As a first step of replacing your refrigerator’s compressor motor, it is important to unplug the unit from the main power point. After unplugging the unit, you can locate the compressor motor at the rear bottom of the refrigerator. Once you have located the motor remove the panel on the lower frontal part of the unit. Once the panel is removed, a thorough check should be done to ensure weather the unit contains a capacitor. If a capacitor is found, carefully remove the wires of the capacitor from the resistor, to prevent any type of shock related accident.

Locating the Relay Terminal

In the second step try locating the relay terminal, which is usually located on the lower side of the back panel. Usually a wire runs from the compressor to this box. Once the panel is removed, you will be able to notice a mesh of wires running in a loop. The panel has a white wire, which is surrounded with copper wires inside the panel. These wires should be removed by unplugging the connector that connects these wires to the relay.

Changing the Faulty Relay or Getting it Repaired

Once you have unplugged the relay, 90 percent of your job is done. All you need to do now is to visit some hardware store and change the faulty relay or get it repaired. Once you get a new relay, plug in the new relay with the connector and replace the panel and your work is done.

Generally a refrigerator sends out various signals, when problem occurs in the compressor, like the fridge not maintaining optimum temperature, there is loud noise every now and then and many such other signals. If you detect these signals early, perform regular service checks and don’t overload your refrigerator, then you can maintain your refrigerators compressor in a good health for a long period of time.
