What Should You Do When Your Refrigerator Makes Noise?

Posted By On 27-12-2022

Some noises coming from your refrigerator are normal and to be expected. These noises are caused by the difference in temperature between the cold internals of the fridge and the warm or even hot outside environment.

If your fridge starts making weird noises, don't freak out. In this guide, we pinpoint exactly what those noises could be and what you should do when you hear them. 

Refrigerator Noises You Could Be Hearing

1) Humming

A thing to remember: all refrigerators make some kind of noise. Usually, they are humming. Humming is their signature noise. The other one is gurgling, which is caused by a cooling gas boiling in the evaporator, which is how the fridge is cooled. 

Other weird noises might indicate a problem, especially if other issues accompany them. In case you notice that the food is not cooling properly or that the ice maker is not working, it warrants a closer look. You can perform a basic diagnosis yourself and maybe deal with the loud refrigerator on your own before calling a repair service.

2) Sizzling Sound

The sizzling sound you hear coming from your fridge is most likely just water droplets falling on the defrost heater. 

This is a common occurrence and is nothing to be concerned about. It is normal for your fridge to make popping and cracking noises in hot environments, and you don't need to do anything about it.

3) Mechanical Noises

A loud noise coming from the back of the fridge is usually due to the condenser fan or compressor. These parts need to be cleaned periodically, as you can see if you look at the dusty back of the fridge.

The first step to cleaning your refrigerator's fan is to unplug it. Once it is unplugged, you can use a soft brush to dust away any debris that has accumulated on the fan blades. If the blades are very dirty, you may need to use a mild cleaning solution to remove all the dirt and grime. Once the blades are clean, you can plug the refrigerator back in and turn it on.

4) Chirping Noises

This is often caused by a loose door seal. If this is the case for you, you can adjust the door seal by loosening the screws that hold it in place. Once you have loosened the screws, you can gently push the door seal into place. Once the door seal is in place, you can retighten the screws.

The fan in the back of the freezer helps circulate air and keeps the freezer temperature consistent. If the fan is not working properly, the freezer will not be able to maintain a consistent temperature, which can cause the food to spoil.

5) Rattling Sound

If you hear any strange or loud noises coming from your fridge, it is likely due to improper installation and not something to worry about. 

The fridge should be on a level surface that is not touching any walls or other objects. If you hear any rattling noises, check to see if the interior contents are touching each other and causing the noise.
