How to quiet a noisy refrigerator compressor: Things you need to know

The compressor is at the center of the refrigerator. It functions by making the refrigerant pressurized and then circulating it through the fridge. The mounts made of rubber are the most frequent location where a compressor can make noise is connected to the fridge. The mounts could be due to an unfastened bolt or clip, or even the mount itself is damaged. However, you could also have a damaged compressor that must be replaced.

How to quiet a noisy refrigerator compressor

Before you take any action to quiet a noisy refrigerator compressor., it’s certainly worth listening to the sounds it produces. Although you may be familiar with them, make sure you know the source of their noise and that they roughly match the description I’ve given previously. If you’re not sure that your fridge’s noises are normal, I’d recommend calling an expert to examine the issue. The increased noise could indicate that components have worn out or are broken, which means that the parts (or the entire fridge) may require replacing. In the same way, you must take note of the items around the refrigerator since it could impact the volume of noise it creates. For instance, the flooring can make a difference since the fridge on a tile floor is likely to generate more noise than one on wood floors.

Step 1

To stop the compressor from roaring to reduce the noise, you’ll need to lift it carefully and remove the refrigerator to reduce the decibels. It is possible to get assistance in this task. Once you’ve pulled out the fridge, disconnect the outlet from the refrigerator to ensure that there’s no chance of being shocked.

Step 2

Before you try to silence the compressor, be sure that the compressor is the cause of the noise. An easy method to find what is causing the noise is by using your fingers to rub the various components of your refrigerator. If you press gently on the details, the loud sound will disappear or increase the volume. First, you need to touch the compressor and the rubber mounts. Do you hear the noise cease or change? If the sound does not change, press on the evaporator, fan, and other refrigerator parts, such as the door.

Step 3

After gently pressing down on the various refrigerator parts, you aren’t sure whether the noise is caused by the compressor or not, unplug from the condenser motor. Its condenser fan can often be the source of annoyances in the fridge. If you unplug the condenser fan and the noise diminishes or stops, the noise is gone, then the compressor isn’t at fault.

Step 4

There is a high possibility that the cause of the sound is near the mounts made of rubber. The brackets or braces connect the compressor in place to the refrigerator. The mounts might be broken or loose and produce a loud noise when the compressor is turned on. The first step is tightening the bolts and fixing the mountains in the fridge. It is necessary to use either a screwdriver or a wrench by the mounts. You can attempt to use some wood shims to tighten the brackets for compressors. Examine the rubber mounts, and replace them if required.

Step 5

If the coils or compressor are dirty, it could be causing the compressor to be over-worked and create loud noises. Clean the compressor, its compartment and cooling coils of dirt and dust. You can purchase special coil brushes for cleaning at many hardware stores.

Step 6

Another alternative is to surround the compressor with acoustic deadening material. You’ll need flexible sheets to put around your compressor. It is essential to ensure that the compressor has adequate ventilation to ensure it doesn’t get too hot. When the decibel level can’t be fixable, one of the methods above the decibel level may need replacement. The first step is to check whether the compressor is in warranty with the manufacturer. If you must cover the cost of replacement, the cost to repair an air compressor (including labor) is in the $200-$650 range, depending on the fridge.

What’s causing a rumble inside your fridge

The search for ways to reduce the noise in your refrigerator is a good idea since it can be very irritating while looking to unwind at your home. It’s still worth finding the source for the sound before attempting to hide it. This noise could indicate something breaking or loose. But fridges are typically noisy devices. A lot is happening within the fridge to keep them cool and protected, especially when you have an integrated fridge freezer. Many of the refrigerator’s sounds are expected, so knowing the root cause before the start is beneficial.

It’s among the most frequent sources of noise because it performs the majority of the jobs. It contains a motor and pump that circulates coolant around the refrigerator and pushes hot air from the back to be discarded. It usually creates buzzing or whirring noises, which are not unusual. If you’re using a contemporary refrigerator that is energy efficient, the compressor is built to operate for long periods and is low; therefore, don’t be shocked when it is on for a considerable time.

The most common sources of noise in the refrigerator

  • The Icemaker (if it’s got one). It can produce many entertaining and alarming sounds, such as buzzing, gurgling and clanging. These are normal and are not the result of the process of making ice.
  • A drip tray. This often makes sizzling and gurgling sounds as well as hissing and dripping. This is entirely normal and just the sounds of water draining from the inside.
  • Walls of the refrigerator. The interior walls of the fridge compartment require the ability to contract and expand when temperatures change. This can cause various cracking, clicking, creaking, and popping normal noises.
  • Compressor. The compressor itself may whirr, hiss and drip, which are normal. There are a variety of liquids through the system, and they’ll produce noise.

The only sounds that you should be concerned by in the case of your refrigerator are the very aggressive ones, but they usually are accompanied by other warning signs. Actually, among the top frightening indicators for a fridge is that it does not make any sound! However, I know that you may find these sounds annoying, as I certainly do. A noisy fridge isn’t an issue if you live in a large home, but it could be a real nuisance if you reside in a smaller house or an apartment.


The first step to quietening the compressor of a noisy refrigerator is to identify the cause that is causing the noise. It might not be the compressor itself; it could be coming from a different component, like the condenser fans. Once you’re sure that it’s the compressor, you’ll need to test some things to reduce the sound. Make sure to check the brackets that connect it to your refrigerator. Sometimes, these mounts made of rubber get damaged; however, it could also be similar to loose bolts or clips. That’s all from how to quiet a noisy refrigerator compressor.
