It’s normal to feel nervous whenever you hear your appliance making a noise. Anything out of the ordinary, including buzzing noises, could signal that something is wrong with your fridge.

Buzzing noises from your refrigerator are normal. However, if you notice louder or more frequent buzzing, it could indicate something is wrong with your refrigerator. 

This article will provide tips to discover why your fridge is making a buzzing noise.


Why Is My Refrigerator Making a Buzzing Noise?

It’s normal for your refrigerator to make some noises as it functions, including buzzing noises. There are plenty of moving parts within your refrigerator, such as the motor, compressor, condenser fans, and ice makers. Keeping these parts operational is hard work; sometimes, the machinery will buzz. 

Particularly since your fridge is running all the time, unlike most other appliances, you will hear more buzzing from it than from something else, such as your dishwasher. 

There are a few times when you will hear more buzzing than usual. If the fridge is working harder than usual (for example, if it is full of food), if it is new and still adjusting various parts, or if the ice maker is running. The freezer also tends to make more noise than the fridge part.

The only time you should be worried about your refrigerator buzzing is when you notice it increasing in frequency or volume, which is often a sign that something is wrong.

Reasons Why Your Fridge Is Making a Buzzing Noise

Although some buzzing is normal when your refrigerator runs, you should stay alert for any changes in its noises as they could signal that something is wrong with your refrigerator.

Sometimes, fixing the buzzing is as simple as moving the fridge to a more stable position or changing an internal bulb. Other times, however, the buzzing signifies something is seriously wrong with your fridge.

These parts are the most common cause of buzzing noises, so start troubleshooting there.

The Compressor

The compressor is one of the most important parts of the fridge. Located at the back of your fridge towards the bottom, it is the mechanism that pumps refrigerant through your fridge. The compressor relies on other parts to work correctly, so if your condenser coil or motor is faulty, it overloads the compressor, causing clanking and loud buzzing.

If you suspect a compressor issue, call a repair service immediately because the compressor is too complicated a part to fix yourself.

Ice Maker

The ice maker is one of the most common causes of buzzing because the mechanism of delivering water and freezing causes a lot of noise. 

However, if you notice more buzzing than usual around the ice maker, that is usually a sign that something is wrong with an internal connection. 

Too many moving parts within an ice maker could cause buzzing, so this is another problem best left to the professionals.

Condenser Coils

The condenser coils on the back of your fridge cool down refrigerant before sending it through your fridge. If you hear buzzing from the back of the fridge, that’s probably a sign that your condenser coils are overheating and working too hard.

The fix for this is usually straightforward. Clean the condenser coils because excess dust and debris affect their ability to function. Cleaning them is easy; unplug the fridge, remove the back panel, and use a small brush or handheld vacuum to clean the dust.


Some buzzing noise is normal as your refrigerator runs, mainly if it is brand-new or having to work harder than usual. Certain fridge parts, such as the freezer or ice maker, cause more noise than others.

Fixing a buzzing noise could be as simple as cleaning your condenser coils. If you suspect one of the more significant parts, such as the compressor, is starting to malfunction, it’s time to call a professional to look at your appliance.
