How to Quiet a Noisy Refrigerator Compressor

In this guide, I will discuss some simple ways on how to quiet a noisy refrigerator compressor.

While some people find these sounds normal, to some, it is disturbing and annoying.

A refrigerator produces different types of noise depending on the items stored in it.

These noises include buzzing, popping, hissing, or gurgling noises, among others.

There are various easy and practical ways to quiet your noisy refrigerator compressor

Let’s get started,

7 Easy ways on How to Quiet a Noisy Refrigerator Compressor

You can simply skip all these DIY hassles and get a new refrigerator. I’ve previously written an article on some of the quietest mini fridges on the market.

1. Locate the Source of the Noise

The first step to fixing a refrigerator noise is locating where the noise is coming from.

A refrigerator makes different noises, which could have different meanings.

For instance, vibrational noise means that you have placed your refrigerator in an uneven position.

Buzzing noise, on the other hand, means that the water inlet valve dispenses water.

But since you already know that the cause of the noise is, you need to narrow down on the different options for minimizing the noise.

The compressor is a notorious part of the refrigerator’s noise production because it is responsible for most of the work.

The compressor also contains the motor and the pump, which also work harder than other parts.

You will often hear either buzzing or whirring when it is overworking or when there is a problem.

The compressor is located on the back of the fridge, which is likely where the noise will be coming from.

2. Level the Legs

To minimize the noise, you should try leveling the refrigerator legs.

Even though this may not be the best solution, it will be a quick fix to the problem.

If you placed your refrigerator on an uneven surface, then that could be the reason why it’s making the noise.

Uneven surface causes the refrigerator to vibrate more, which is the noise you are hearing.

It would be best if you place it on a more even surface.

Since most refrigerators have adjustable legs, you could try checking to see if they are appropriately leveled.

The legs can become loose or uneven over time; it is best if you check them regularly.

If you have no idea whether the fridge is uneven, a simple test involves rattling it slightly.

If it moves, then you know it’s uneven.

3. Soundproof the Fridge

It would help if you soundproofed behind the fridge since this is where the compressor coils are located.

Water passes through these coils to release any extra heat energy.

Knowing this will help you find the right way to soundproof the fridge without covering up the back too much as it could cause overheating, which is bad.

Overheating could cause the compressor to overwork and, consequently, breakdown.

So one of the best solutions you should consider is, soundproofing the wall behind the fridge.

You should use both sounds blocking products and acoustic products to ensure that the noise is greatly minimized.

You could use acoustic blankets or acoustic foam to prevent the noise.

Ensure you leave a small gap between the wall and the fridge to allow easy airflow.

Soundproofing the wall behind the fridge ensures that the noise does not leak to the house’s other areas.

4. Use Vibrational Mats

Vibrational mats are necessary to help eliminate noise caused when the fridge interacts with the floor.

Place the vibration mats on the floor, then place the refrigerator on top of it.

The idea is to create sufficient distance between the refrigerator and the floor to reduce vibrations’ chances.

You could also use anti-vibrational feet instead of the mats.

Be sure to ask a friend for some help to lean the fridge on one side as you slide the rubber feet underneath.

The rubber feet and the mats both absorb the vibration and minimizes the noise.

5. Build a Cabinet for the Fridge

You could also build a cabinet for the fridge to help minimize the noise from leaking out.

You can purchase a ready-made box or build one from scratch.

When building the box, you need to keep the fridge’s measurements in mind.

You don’t want to build something too small for the fridge not to fit or one that is too big to lead to more problems.

A little extra space is not as bad as it helps to prevent overheating.

The extra space allows you line the inside of the box with soundproofing materials that will further minimize the noise.

You could line the cabinet with acoustic foam or sound deadening mats.

The other product you can use is mass-loaded vinyl(MVL), even though it might be a bit close.

You can use one product or a combination of different products as long as they are best at noise reduction.

Follow these steps when you want to build:

  • Start by measuring the refrigerator’s size, then use those measurements to cut the MDF and ensure you add a few inches.
  • You can attach the MVL to the MDF using glue or pin them together using nails.
  • Cover the MVL with a sheet of acoustic foam, then attach it behind the fridge.

6. Call the Professional

If fixing the compressor noise by yourself seems like a tough job, then you need to ask for a professional’s help.

A professional will know where the problem is and how to repair it

Though you may have to part with some cash, it will be worth it at the end of the day.

A professional will also tell you whether the compressor is damaged and whether you need to repair it or buy a new one.

The good thing about a professional’s help is that they can also tell if there are other issues besides the compressor.

7. Buy a New Quiet Fridge

If all else fails, you should consider buying a new fridge that is quiet.

Though this option will force you to spend money, it will be worthwhile in the end.

Fridges make noise, especially if they have been in use for a long time.

Remember, continued use will make the refrigerator parts wear out, which in turn leads to noises.

When purchasing a new fridge, remember to pay attention to some of these factors:

  • Ratings

Check the user ratings when purchasing a new fridge.

Reviews from previous customers can tell you so much about the fridge and whether it will have issues.

  • Age

The age of the fridge will matter a lot in terms the noise production.

If your fridge is older, then you need to upgrade to a new one.

  • Energy Efficiency

A fridge that is energy efficient means that its compressor will be quieter compared to the older fridges.

Final Thoughts On How To Quiet A Noisy Refrigerator Compressor

Knowing the practical hacks on how to quiet a noisy refrigerator compressor has less to worry about.

Before trying the methods, first, ensure that your refrigerator is not faulty.

Most of the above methods have high chances of not working if the refrigerator is faulty.

However, note that you don’t have to buy the whole new appliance; instead, you can purchase new parts to replace the old and faulty ones.

For better results, you can combine two or three methods.
