Best Ways To Fix When Refrigerator Making Noise

A refrigerator is one of the most important appliances in any household. It is used for storing different food items, and it helps to keep them cool. However, if my refrigerator is making a loud humming noise, maybe it’s the compressor.

Do you hear a refrigerator making a humming noise or has your refrigerator simply stopped working all of a sudden? The reasons for refrigerators making noises can range from a simple fix to needing a new fridge. Either way, this article explains the causes and how to troubleshoot them.

Why is My Refrigerator Making Noise?

Why is My Refrigerator Making Noise

Fridges make all sorts of noises, but one you might not expect is the sound of popping. The reason your fridge makes these noises will depend on the type of noise and what’s happening inside your fridge.

Thermal Expansion

The most common reason a fridge makes popping noises is thermal expansion. As the temperature within the appliance changes, there are times when it expands or contracts more than usual.

When this happens, it can cause small explosions that can be heard outside the appliance. You may also see your food moving around when thermal expansion takes place.


Another reason for popping noises is vibrations from motors or other parts of your fridge moving too fast or too slowly.

This can happen if there’s something wrong with the motor or if something has caused it to overwork itself. If you notice that your food isn’t staying cold enough, this could be why. The same goes for any other type of strange behavior from your fridge.

A Water Valve Issue

The final thing you’ll want to check is whether or not your water dispenser is working properly. If you don’t use your water dispenser often, it may have dried up and become clogged with minerals. This will cause pressure in the pipes, which can cause a popping sound when you turn on the water dispenser.

This problem can usually be fixed by flushing out the system using vinegar or baking soda. You can also purchase a product called CLR that will help clean out your pipes as well.

Steps to Fix When Your Refrigerator Makes Noise

Steps to Fix When Your Refrigerator Makes Noise

If you have a refrigerator that is making noises, it may be time for some maintenance. There are a few steps you can take to address the problem.

Listen For The Source

The first step is to listen for the source of the noise. If you can pinpoint the exact location of the sound, you will have an easier time finding a solution. You can also open and close doors and drawers in your refrigerator to see if it gets louder or softer in certain areas.

Secure The Drain Pan

If your fridge is making a clunking sound, this could be due to loose parts or something banging together as it moves around inside the machine. To fix this issue, make sure that all drain pans are secured properly so they cannot move around when the compressor kicks on and off.

Listen And Look For A Faulty Defrost Timer

If your refrigerator makes a clicking sound every few seconds, it may be due to a faulty defrost timer.

This component is responsible for switching on and off the defrost heater periodically. If it malfunctions or gets stuck in the “on” position, it will continue running until you notice the problem and turn it off manually.

You should also check if there is any ice buildup on the back wall of your freezer compartment—this could also cause your appliance to make unusual sounds.

Clean And Inspect The Condenser Fan

The condenser fan is located at the bottom of your compressor and draws air through the coils to cool them down. The fan blade can get dirty, which will cause it to make more noise than usual. Cleaning this fan with warm water and soap will solve this problem.

Check The Evaporator Fan

If you hear a humming sound coming from your refrigerator, this may be caused by an issue with your evaporator fan.

This fan draws cold air into the freezer so that it can freeze food quickly. If there is any dust or debris on this fan, then it may cause it to make more sounds than normal while running.

Cleaning this part with warm water should solve this problem as well.

See If It’s Refrigerator Compressor Noise

Suppose your refrigerator makes loud noises every time you turn on the appliance. In that case, it could be because of an air leak in the system or for some other reason related to refrigeration components, such as the condenser fan motor or evaporator fan motor failing to start up properly after getting stuck during operation. The cause may be due to some obstruction in its paths like lint build-up or debris blocking the working area that causes it to malfunction and produce loud noises while operating.

Why Does My Refrigerator Make Noise At Night?

Refrigerators are generally quiet appliances. When they make noise, it’s usually because there’s a problem.

If your refrigerator is making strange noises at night, there could be a few reasons why this is happening. The most common reason is that the food in your refrigerator has shifted and is hitting against the sides of the appliance or knocking into other items inside. This can cause some noise and vibration that you can hear from another room.

Another possible cause of fridge noise at night would be if you have an ice maker that has frozen up and is now making loud noises as it thaws out. You will likely need to call an appliance repair professional if this happens because it can be dangerous to try and fix it yourself without the proper tools and knowledge required for working with electricity and other hazardous materials found in refrigerators like freon gas.

Can A Noisy Fridge Cause A Fire?

The short answer is: yes, it can. But the long answer is more complicated. A noisy refrigerator can be a major nuisance and an expensive repair bill waiting to happen. But if you ignore the problem, it could cause more serious damage than just annoying your family members. A noisy refrigerator may be a sign of an impending fire or other dangerous situation.

The noise might be caused by an electrical short circuit in one of the components or by some other problem with the appliance itself. If you’re hearing strange noises coming from your refrigerator, you should get it checked out by an appliance repair technician as soon as possible to avoid further problems down the road.

When Should I Worry About My Fridge Noise?

If your fridge is making any unusual noises, it’s important to have the problem diagnosed as soon as possible. A noisy fridge can be a sign of serious issues with the appliance, which could lead to more costly repairs in the future.

Here are a few signs that your refrigerator may need repair:

  • A rattling sound is coming from inside the unit
  • A humming or buzzing noise comes from the compressor
  • An excessively loud cooling fan
  • A clicking or knocking sound comes from the compressor
  • A humming sound is coming from behind the cover panel on top of your refrigerator.

In Closing

In the final analysis, figure out what type of noise your refrigerator is making or why the refrigerator is making noise, and locate the source of the problem. If the cause is a simple one that you can handle yourself, like a freezer shelf that has slipped out of place, then it’s nothing to get too worked up about.

Likewise, it isn’t worth rushing out and spending money on repairs if you don’t know what’s going on. If you are in doubt, however, or if you feel confident that there is something wrong with the refrigerator and you can’t fix it yourself, it’s time to call in a professional who can diagnose and remedy the problem.
