Is your refrigerator making a loud, annoying noise? It could be a sign that your compressor is struggling to function properly.

A noisy compressor can be a major nuisance, but the good news is that there are a number of easy and quick ways to fix the problem.

In this article, we'll share 7 solutions for quieting a noisy refrigerator compressor that you can try right away.

But before we get started, let's take a quick look at some of the causes and consequences of a noisy compressor.

1Causes of a Noisy Compressor

There are several factors that can cause a refrigerator compressor to make noise.

These include:

  • Dirty condenser coils

    If the coils on the back of your refrigerator are dirty, it can cause the compressor to work harder than it needs to and create a loud noise.

  • Loose compressor mounts

    If the mounts that hold the compressor in place are loose or worn, it can cause the compressor to vibrate and make a rattling sound.

  • Unlevel refrigerator

    If your refrigerator isn't level, it can cause parts to vibrate and create a loud noise.

  • Worn or damaged fan blades

    If the blades on your refrigerator's fan are worn or damaged, it can cause the fan to be misaligned and create a loud buzzing or whirring sound.

  • Faulty start relay

    If the start relay on your refrigerator is faulty, it can cause the compressor to make a clicking or humming sound.

 

2Consequences of a Noisy Compressor

Aside from the annoyance of a noisy compressor, there are a few consequences that you should be aware of.

For example, a compressor that's working harder than it needs to can consume more energy, which can result in higher energy bills.

Additionally, an overworked compressor can wear out faster, which could lead to the need for a costly repair or replacement.

With that in mind, let's dive into the 7 quick and easy ways to quiet a noisy refrigerator compressor.

step: 2.1

Clean the Condenser Coils

One of the most common causes of a noisy compressor is dirty condenser coils. Over time, dust and debris can accumulate on the coils, which can cause the compressor to work harder than it needs to.

To clean the coils, simply unplug your refrigerator and use a vacuum cleaner or brush to remove any visible dirt or debris.

You can also use a specialized coil cleaning brush or a can of compressed air for a more thorough cleaning.
