DIY Guide: How to Fix Your Fridge Compressor Like a Pro

The refrigerator compressor is the heart of your fridge. It’s a motorized pump that circulates the refrigerant through the coils of the fridge to keep your food and drinks cold. Without the compressor, your refrigerator would be just a box, so it’s crucial to know what it is and how to locate it in order to understand how to fix a fridge compressor. If you are interested in the way your refrigerator works or are thinking about how to fix a noisy fridge compressor, this guide is for you.

How Does It Work?

The compressor works by compressing refrigerant gas, which then circulates through the fridge’s coils, absorbing heat and cooling the air inside the fridge. It’s an essential part of your refrigerator’s cooling system, and if it’s not working correctly, you’ll need to order a fridge repair service since your appliance won’t cool properly.

The unit has several components, including a motor, an electric starter, and a capacitor. The motor powers the compressor pump, while the starter and capacitor help the motor start and run smoothly.

What Are the Most Common Signs of Compressor Issues?

There are several signs to look out for that indicate you may have a problem with this refrigerator part. Here are some signs to look out for indicating that you may be interested in learning how to fix fridge compressors.

• The fridge is not cooling: The most obvious sign that you have a compressor problem is if your fridge is not cooling correctly. If your refrigerator is not maintaining a consistent temperature, or if the temperature is too warm, it could be a sign that the component is not functioning correctly.
• The appliance is making strange noises: If you hear strange noises coming from your refrigerator, such as buzzing, clicking, or humming, it could be a sign that the compressor is struggling to function correctly. These noises could indicate a problem with the component’s motor, starter, or capacitor, so you’ll have to search for how to fix a noisy fridge compressor.
• The fridge is vibrating: If your refrigerator is vibrating excessively, it could be a sign that the component is struggling to function correctly. This vibration is usually caused by an unbalanced compressor or a unit that is working too hard to keep the appliance cool.
• The fridge is leaking refrigerant: If you notice a leak or a buildup of frost in or around your refrigerator, it could be a sign that the compressor is leaking refrigerant. A refrigerant leak is a serious problem that can damage your fridge and pose a health risk, so it’s essential to address it promptly.
• The appliance is overheating: If your fridge is overheating, it could be a sign that the compressor is working too hard to keep the refrigerator cool. This can be caused by a variety of issues, including dirty condenser coils, a clogged filter, or a malfunctioning component.

How to Locate the Fridge Compressor?

Identifying the unit and its components is essential if you need to troubleshoot or replace it. Locating the fridge compressor is relatively easy, as it’s typically located at the back of the fridge, near the bottom. However, some fridges have the compressor in a different location, such as on top of the unit or even underneath.

So before you read about how to fix a fridge compressor, here are the steps to locate the unit:

1. Unplug the fridge: Always unplug the appliance before attempting any repairs or maintenance.
2. Remove the back panel: To access the unit, you’ll need to remove the back panel of the refrigerator. This panel is usually held in place with screws or clips.
3. Look for the compressor: Once you’ve removed the back panel, you should be able to see the unit. It’s a cylindrical component with copper tubing attached to it. You’ll also notice the motor, starter, and capacitor.
4. Identify the model and serial number: Make a note of the component’s model and serial number. This information is essential if you need to replace it.
5. Replace the back panel: Once you’ve located the compressor and made note of the model and serial number, you can replace the back panel and plug the refrigerator back in.

How to Fix the Fridge Compressor?

Replacing a compressor can be expensive, but with a few tools and some basic knowledge, you can fix your fridge compressor like a pro in a DIY process. Here is how to fix fridge compressors:

1. Safety First

Before attempting any refrigerator repairs, always unplug the unit and discharge the capacitor to avoid electric shocks. Also, use gloves and protective eyewear when handling sharp or heavy parts.

2. Troubleshoot the Compressor

If your fridge is not cooling properly, the first step is to check the compressor. Use a multimeter to test the windings of the component for continuity. If there is no continuity, the unit is dead, and you will need to replace it. If there is continuity, move on to the next step in the guide on how to fix a fridge compressor.

3. Check the Start Relay and Capacitor

If the compressor is running but not cooling, the start relay or capacitor may be the problem. Remove the start relay and shake it to see if it rattles, indicating a bad connection. You can also test it with a multimeter. If the relay is defective, replace it. Similarly, the capacitor can be tested with a multimeter and replaced if defective.

4. Clean the Condenser Coils

Dirty condenser coils can cause the unit to overheat and fail. To clean them, unplug the refrigerator and locate the coils behind the grille or at the back. Use a brush or vacuum to remove any dust or debris. You can also use a coil cleaning spray for a more thorough cleaning.

5. Replace the Compressor

If none of the above steps work, and your fridge compressor is still not functioning correctly, then it’s time to replace it. You will need to purchase a replacement unit that matches your fridge’s make and model. The process involves removing the old component, installing the new one, and recharging the system with refrigerant. It’s recommended to seek the help of professional technicians who know well how to fix fridge compressors if you are not experienced.

In conclusion, fixing your fridge compressor like a pro requires some basic knowledge, tools, and a little patience. You can troubleshoot the compressor, check the start relay and capacitor, clean the condenser coils, and replace the component if needed. However, it’s essential to prioritize your safety and seek professional help if you are not sure about any issue, for example, how to fix a noisy fridge compressor. With these DIY tips, you can save money and keep your refrigerator running smoothly for years to come.
