How to Fix a Refrigerator Compressor

Hello and welcome! Today, we will be discussing the topic of how to fix a refrigerator compressor. The compressor is a vital component of a refrigerator, responsible for keeping its contents cold. A malfunctioning compressor can result in an ineffective fridge and spoiled food. Thus, understanding how to fix a faulty compressor can save you time and money. In this guide, we will outline the steps to address compressor issues and what tools you may need to do so. Let’s get started!

Understanding the Function of a Refrigerator Compressor

A refrigerator compressor is an essential component in any refrigerator. It is responsible for compressing and circulating refrigerant gas through the coils of the refrigerator’s cooling system. The compressor is a motor that is powered by electricity and is located at the back of the fridge or at the bottom.

The Role of the Compressor in Cooling the Refrigerator

The compressor plays a significant role in cooling the refrigerator. When the compressor is turned on, it creates a low-pressure area that draws in the refrigerant gas. The gas is then compressed and pushed through the coils, where it condenses into a liquid. As it cools, the liquid refrigerant absorbs heat from the interior of the refrigerator, which cools the air.

Common Issues with Refrigerator Compressors

A malfunctioning compressor can cause significant problems in your refrigerator. Some common issues include:

  • The refrigerator is not cooling properly
  • The compressor is making strange noises
  • The compressor is running hot
  • The compressor is not turning on at all

Troubleshooting a Refrigerator Compressor

Checking the Power Supply

The first thing to check when troubleshooting a refrigerator compressor is the power supply. Ensure that the fridge is plugged in and that the circuit breaker has not tripped. If the power supply is not the issue, move on to the next step.

Checking the Thermostat

The thermostat is responsible for regulating the temperature inside the refrigerator. If the thermostat is not functioning correctly, it can cause the compressor to stop working. Check the thermostat by turning it up or down to see if the compressor kicks on.

Testing the Start Relay

The start relay is a small device that regulates the power supply to the compressor. It is located on the side of the compressor and can be removed for testing. Use a multimeter to check if the start relay is functioning correctly. If it is faulty, replace it with a new one.

Checking the Capacitor

The capacitor is another critical component of the compressor. It stores electrical energy and provides an extra boost to the compressor when it starts up. Use a multimeter to test the capacitor, and if it is faulty, replace it with a new one.

Replacing the Compressor

If none of the above steps have resolved the issue, the compressor may need to be replaced. Replacing a compressor is a complicated and costly process that is best left to a professional.

FAQs for How to Fix a Refrigerator Compressor

What is a refrigerator compressor?

A refrigerator compressor is a motorized device that compresses refrigerants, which are responsible for cooling the refrigerator. It is located at the back of the refrigerator and is responsible for compressing and circulating refrigerants through the coils of the refrigerator.

What are the signs that a refrigerator compressor is faulty?

If you notice that your refrigerator is not cooling as it should, it could be a sign that the compressor is faulty. Other signs include the refrigerator making strange noises, the compressor motor running continuously or not running at all, and the failure of the compressor fan to work properly.

How do I fix a faulty refrigerator compressor?

Unfortunately, fixing a faulty refrigerator compressor is not always a simple task. If the compressor is completely broken, then the only solution is to replace it with a functional one. If you have experience with repairing electrical appliances, you can attempt to fix simple issues such as replacing the start relay or capacitor. However, if you are not confident in your abilities or unsure about the cause of the fault, it is best to seek professional help.

Can a faulty compressor be repaired?

In some cases, a faulty compressor can be repaired, but this is not often guaranteed. If the compressor motor has burnt out or the compressor coils are damaged, then it may be beyond repair. In other cases, if the issue is related to the compressor start relay or capacitor, these can be easily replaced.
