In this blog, we’ll discuss what a bad refrigerator compressor sounds like and how to troubleshoot it with HA Fixer.

What is a Refrigerator Compressor?

Before we dive into the topic, it’s essential to understand what a refrigerator compressor is and what it does. The compressor is a vital component of a refrigerator, and it’s responsible for compressing the refrigerant gas and circulating it through the system to cool the interior. The compressor consists of a motor and a pump that work together to compress the refrigerant and move it through the system.

What Does a Bad Refrigerator Compressor Sound Like?

A refrigerator compressor can produce several sounds, and not all of them are a sign of a problem. However, some sounds are an indication that the compressor is failing or has failed.

Here are some of the sounds you might hear if your refrigerator compressor is bad:

Clicking Sounds

If you hear a clicking sound coming from your refrigerator, it could be a sign that the compressor is trying to start but failing. This clicking sound can indicate a problem with the start relay, which is responsible for providing power to the compressor motor.

Humming or Buzzing Sounds

If you hear a humming or buzzing sound coming from your refrigerator, it could be a sign that the compressor is running but not starting. This sound can indicate a problem with the start capacitor, which is responsible for providing the initial boost of energy needed to start the compressor.

Rattling or Vibrating Sounds

If you hear rattling or vibrating sounds coming from your refrigerator, it could be a sign that the compressor is failing. This sound can indicate that the compressor is not working correctly, and the internal components are loose or damaged.

Hissing Sounds

If you hear a hissing sound coming from your refrigerator, it could be a sign of a refrigerant leak. A refrigerant leak can cause the compressor to overheat and fail, resulting in a hissing sound.

Grinding Sounds

If you hear a grinding sound coming from your refrigerator, it could be a sign that the compressor is failing or has failed. This sound can indicate that the internal components of the compressor are rubbing against each other, which can cause damage and eventually lead to failure.

How to Troubleshoot a Bad Refrigerator Compressor Sound?

If you hear any of the sounds mentioned above coming from your refrigerator, it’s essential to troubleshoot the issue immediately. Here are some steps you can take to troubleshoot a bad refrigerator compressor sound:

Check the Power

The first thing you should do is check the power supply to your refrigerator. Make sure it’s plugged in and receiving power. If there’s a power outage, wait for it to come back on, and then check the refrigerator again.

Clean the Coils

Dirty condenser coils can cause the compressor to overheat and fail. Check the coils at the back of the refrigerator and clean them if they’re dirty. Use a vacuum cleaner or a soft brush to remove any dirt or debris that’s clogging the coils.

Check the Start Relay

If you hear a clicking sound coming from your refrigerator, it could be a problem with the start relay. The start relay is responsible for providing power to the compressor motor. You can test the start relay by unplugging the refrigerator and removing the relay from the compressor. Shake the relay gently and listen for any rattling sounds. If you hear any rattling sounds, the relay is faulty and needs to be replaced.

Check the Start Capacitor

If you hear a humming or buzzing sound coming from your refrigerator, it could be a problem with the start capacitor. The start capacitor is responsible for providing the initial boost of energy needed to start the compressor. You can test the start capacitor by unplugging the refrigerator and removing the capacitor from the compressor. Use a multimeter to test the capacitor for continuity. If the capacitor doesn’t have continuity, it’s faulty and needs to be replaced.

Check the Compressor Motor

If you hear any strange noises coming from the compressor, it could be a sign that the motor is failing or has failed. You can test the motor by unplugging the refrigerator and removing the motor from the compressor. Use a multimeter to test the motor for continuity. If the motor doesn’t have continuity, it’s faulty and needs to be replaced.

Check for Refrigerant Leaks

If you hear a hissing sound coming from your refrigerator, it could be a sign of a refrigerant leak. A refrigerant leak can cause the compressor to overheat and fail. You can check for refrigerant leaks by inspecting the coils and the connections between them. Look for any signs of oil or coolant leakage, and if you find any, contact a professional to fix the leak.

A bad refrigerator compressor can cause various noises, and it’s essential to troubleshoot the issue immediately to prevent further damage. By understanding what a bad compressor sounds like and how to troubleshoot it, you can save money on repairs and prevent food spoilage. If you’re not comfortable troubleshooting the issue yourself, it’s always best to contact a professional, like HA Fixer, who can diagnose and fix the problem. Remember to keep your refrigerator clean and well-maintained to prevent future problems and prolong its lifespan.
