Fridges can be noisy, but that’s not to say they are quiet. Refrigerators are noisy because there is so much going on inside to keep them cool and insulated. This is especially true if they have a combination freezer/fridge. Many of the sounds a refrigerator makes are normal. It is important to identify the cause before you start.

Because it does most of the work, the compressor is the main source of the noise. It consists of a motor and a pump. The compressor moves coolant through the refrigerator and pushes hot air out the back to make it waste.
These sounds are normal and can be described as whirring, buzzing, or buzzing. Modern energy-efficient refrigerators have a compressor that is designed to last long and low. Don’t be surprised if your fridge stays on for a while.
The following are other common noise sources in refrigerators:
- Suppose it has one, the ice maker. You may hear gurgling, buzzing, and clicking. These noises are normal and part of the process of making ice.
- The drip tray. You may hear gurgling, sizzling, and hissing sounds. These sounds are normal and sound like water is being drained from the interior.
- Refrigerator walls. The fridge compartment’s interior walls must expand and contract with temperature fluctuations. These sounds are normal and can be heard clicking, cracking, or popping.
- The compressor. The compressor can make noises like whirring, hissing, or drip. These are all normal. Different liquids flow through the system, and they will make noise.
Another perspective on noise from refrigerators is:
The only sound you should be concerned about when it comes to your fridge is an angry one, although other warning signs can often accompany these. The fridge making no noise is one of the most alarming signs.
These noises can be annoying, but I understand why. If you have a large house or apartment, a noisy refrigerator is not a problem. However, it cannot be very pleasant.
Fixing Noise Coming From the Back of the Fridge
If your fridge is making a lot of noise, it’s worth taking a look at the three main components of your fridge, which are the compressor, condenser fan, and defrost timer. You will find the condenser fan near the back of your fridge. A panel often covers it.
It is normal for the fan to make a hissing sound during the day if dust or lint is stacked between its blades.
To resolve this issue:
- Unplug your refrigerator.
- Locate the condenser fan.
- Use a soft brush to clean each fan blade until you find no debris. If there isn’t any dust, it may be time to change the fan’s motor.
Modern fridges have a quiet compressor. A noisy compressor can be a sign that your fridge is in serious trouble. In most cases, you should replace it immediately.
A compressor is also associated with your refrigerator’s gas and pressure. The noise from the compressor is a sign that your refrigerator is not being maintained properly or is under pressure.
You can replace the entire defrost timer if you discover that it is making noise.
1. Level out the legs
This may not be affecting the compressor’s performance, but it is one of the easiest problems you can solve. An uneven or low-density floor can make a fridge produce more noise than usual.
The floor surface can make a huge difference in reducing noise. These vibrations are more difficult to pass through tile than wood. It is important to address this issue.
First, I would check the legs of the fridge. Most refrigerators come with adjustable legs that allow you to adjust them individually. This can be a huge help with uneven surfaces and solves your problem fast.
These legs can also become loose or move due to vibrations over time. Even if they were properly set when the fridge was first installed, it is worth checking again.
This is easiest done by giving your fridge a rattle. Adjust the legs if it moves. You might consider getting someone else involved so they can shake the fridge, and you can watch the legs or vice versa.
Although it might seem tempting to take a spirit level measurement out there, I would not. Stable and even are two distinct things. Your refrigerator may be stable but wobbly if it is on an uneven floor. Pay attention to the legs and remember that the fridge should not wobble at all.
2. Try and Make Sure It’s the Right Size for You
This may seem strange. This may sound strange. The fridge’s capacity is a key component of keeping it cool. The fridge should be full to prevent items from freezing and maintain temperature. The compressor will need to work harder to maintain a cool temperature if it is half full.
A fridge that is too big will make noise more noticeable. You should get one that is 75% full.
You can also put water bottles on the bottom shelf of the fridge. This helps me keep my fridge full while also making it easier to drink more water.
3. Put the fridge on a mat
You can adjust the legs, but your fridge vibrates on the floor. If this happens, you should consider putting the fridge on a mat. This will require something more sturdy than a regular rug, but some products can do this.
There are many products in the soundproofing industry called sound deadening mats. These are typically used to dampen engine noises inside vehicles. This is more or less what we are trying to solve!
Hushmat and Dynamat, two of the many manufacturers of sound-deadening mats (Amazon links), offer products that can be used in the home. These products are not the same as their vehicle products. They don’t usually include thermal insulation because this isn’t something you will need in this situation.
The mats are designed to be used with appliances such as washing machines and refrigerators. The mats have proved to be very useful in this task, and I have one under each appliance in my home.
Butyl rubber is used to make the mats. It is a dense material that has very little elasticity. It absorbs sound waves and vibrations very well. Although the mats are usually less than one inch thick, they do a great job.
If you don’t have the right product, mass-loaded vinyl or vehicle sound deadening pads will work. Make sure you measure the dimensions of your fridge and the floor beneath it before cutting the mat.
4. Install an intake silencer
The intake is one of the main sources of noise from a refrigerator compressor. A silencer can be installed to reduce noise from the compressor’s intake. These devices are made up of two parts: an air filter and a silencing device.
Can I extend my intake outside of the house?
The best way to reduce the noise from your compressor is to put the intake piece outside. This is a cheap and effective solution. How do you do that? You can do this by using a pipe to extend your intake and place it outside your home.
If you want to test this solution, it is important to place the refrigerator in an area with sufficient outdoor space. It’s not as efficient as using a soundproof material around your motor, but it can still be very helpful.
5. Perform Maintenance
Refrigerators can be difficult, so it is a good idea to hire a professional. You can try it yourself if you are a skilled repairman. Safety first, make sure the item is unplugged before you begin!
You should be able to see the fan by removing the back panel. You can check to make sure the fan is not damaged. If necessary, vacuum the area to remove dust and dirt.
The fan should be dried with a clean, damp cloth. Ensure that the fan is securely fastened and not loosening while you do this. If it’s loose, tighten it or replace it altogether.
The compressor can now be inspected. It would help if you looked for signs such as rust, missing pieces, or wear. You can investigate replacing it if you find damage.
You might consider replacing the fridge if this isn’t cost-effective or the fridge is very old. Modern fridges do not use compressors, which would eliminate the noise problem.
6. Put the refrigerator in an alcove
Moving your fridge into a nook is one of the best ways to block the sound waves coming from it. This will trap sound waves in a smaller area and make them less likely to bounce around.
This allows you to soundproof the fridge’s sides as well as the back. While you can attach things to the sides of the fridge, I would still recommend soundproofing the alcove. This will make it much easier to reach the fridge in case of an emergency.
You can build a soundproof board similar to the one shown above. However, it would help if you also made two other boards the same size as your sides. As air will circulate the refrigerator, I recommend leaving at least 1 to 2 inches between it and the sides. This will make it less likely to overheat.
But, it’s worth paying close attention to your fridge for at least a day after you have moved it. Soundproofing has several benefits, but one of them is that it can also improve thermal insulation.
A fridge requires air to circulate its coils to cool it, as I have already explained. A fridge surrounded by foam tiles or acoustic insulation will have a harder job losing heat energy. This could lead to it becoming more susceptible to breakdown.
However, this is not always the case. If you do it correctly, you shouldn’t have any problems. It is important to keep an eye on the device and remove it from the wall if it becomes too cold or hot. These are indicators that you may need to go back to the drawing boards with your soundproofing solutions.
7. Soundproof Your Refrigerator From the Inside
A good alternative is to soundproof your refrigerator inside. There are many options, but the most popular is mass-loaded vinyl (as I have already mentioned).
It is a material that blocks the transmission of sound around a location so that it can deprive your fridge of its sound.
You could also place mass-loaded vinyl around the fridge’s motor for better results. You can also use this material on the wall surrounding the fridge rather than using an acoustic dampener. You can also place a thin piece of vinyl under your refrigerator to ensure no sound escapes.
8. Build a shelving unit around the fridge
However, not everyone has a spare nook in the kitchen. You can also build a shelf unit around your refrigerator. This will require some space, and you should have some DIY skills.
The idea behind building a unit around a fridge is to add mass to the area to absorb more noise. If done correctly, this solution can be quite effective.
Because it will depend on how much space you have, I won’t detail how to build a shelving unit. You might like to see the video below.
Soundproofing the fridge in the same manner as I suggested above is the key, but still leaving enough room for proper airflow.
You are building an alcove to soundproof and store your refrigerator.
Another benefit to building such a unit is the ability to fill it with stuff. This adds mass to the structure. Heavy and dense objects are the best choice.
However, I would avoid pots, pans, and plates as they can cause your fridge to vibrate, which will make it rattle. This will only make the problem worse, not solve it.
9. Regularly Clean the Compressor and the Fans
A dirty compressor or fan can cause unwanted noise. You can fix this problem by cleaning out the fan and compressor. Also, make sure to check the coil to ensure it is working correctly.
10. Buy a new quiet or less noisy fridge
It is possible to find out that your refrigerator is not as quiet as you thought. Older fridges can be very loud. This is especially true if parts get worn out and aren’t economically feasible to replace.
When you’re looking for a new fridge to fit your needs, some things will affect the noise it makes. These are:
It is energy efficient. It is quieter than older refrigerators and has a compressor that runs longer and lower. Avoid energy-efficient refrigerators if you are averse to noise.
Is it equipped with a fan? Many compact fridges and smaller ones don’t have fans as part of their cooling system. Although this information might not be easily accessible, a fridge that does not have a fan will make less noise.
The fridge’s age. You should upgrade if you are looking. However, this advice also applies to secondhand fridges. The more efficient and quieter the fridge is, the better.
