How To Fix My Refrigerator Making A Buzzing Sound?

These sounds are made by the various components on the machine that is there to ensure that the temperature inside the fridge remains at a good level.

However, sometimes these sounds can become too loud. Especially if you hear a buzzing noise that is different from the others that you are used to then you need to consider taking a look into the fridge and figuring out what may be causing it.

Let us begin with the most common and overlooked issue:

How To Fix My Refrigerator Making A Buzzing Sound?

Fridge alignment:

Empty your fridge:

Hence start by removing all the magnets and other items on top of the refrigerator to make sure it’s completely free of any attachments.

Then start working on the inside by making some space between the items placed inside. When the items inside have ample space between them you can have a good estimation of what must be causing the sound. If the buzzing noise still persists you can place everything back inside and do a bit more digging.

Inside and outside the refrigerator:

Now you are left with two main places to look for the sound. That is the interior and the exterior of the fridge. Let’s first start with the inside.

Faulty evaporator motor:

Every refrigerator comes with an evaporator fan inside the fridge that helps keep the contents inside cool. You need to now locate the evaporator fan.

Before you do anything do not forget to empty the refrigerator and ensure that the perishable items are securely placed. Now start working on the evaporator fan.

Once you have located it, you must look for any issues such as the fan not working properly or being extremely dirty that may be causing an obstruction. You can remove the fan and give it a thorough wash.

Once you put your fan aside to dry look for the grommet and the motor of the evaporator fan. Place the fan back on and see if the motor and the grommet are functioning properly. The fan should be able to rotate without any obstruction and noise. That will ensure that this part of the refrigerator is not the issue.

Now let’s look at the exterior of the refrigerator.

Inlet valve issues:

The inlet inside the refrigerator’s ice-making or water dispensing unit can also be a serious cause for all the buzzing sounds. For this, you will have to power off the machine and find the water hose that is plugged behind the refrigerator.
