Fridge and freezers are bound to make some whirring and other kinds of sounds due to the cooling that needs to be done. The sounds can range from whirring, cracking, popping, and hissing as well.
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.
There are 5 main reasons why such sounds can be heard from the fridge. We will not only mention the reasons but also guide you on how to fix them.
Let us begin with the most common and overlooked issue:
How To Fix My Refrigerator Making A Buzzing Sound?
A fridge that is not placed on an even ground can also be the cause for a buzzing sound. To remove this issue, you can check by using a bubble level on top of the fridge to see if it aligned correctly. If it is not stable then you can find some folded papers to place underneath the feet of the fridge to align it better.
You can also buy anti-vibration pads to place underneath the refrigerator. This will prevent the fridge from making any buzzing sounds and will start functioning properly.
Empty your fridge:
There are sometimes items inside or outside the fridge that can be causing these sounds. Such as magnets on the fridge or Tupperware placed inside the refrigerator can also cause these issues. 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.
Through that, you will be able to locate the inlet valve. If the inlet valve is malfunctioning and not providing sufficient water supply to the fridge, that may be one of the reasons you may be hearing a buzzing sound.
Unfortunately, if the inlet valve is broken or malfunctioning you can get it repaired it has to be replaced. However, if you do have a warranty you can simply ask the manufacturer to repair the product.
Compressor and condenser malfunction:
Last but not the least, your fridge may be making these buzzing sounds due to the compressor or the condenser. To go through with the cleaning of the condenser coils firstly, switch the fridge off. The next step would be to let it cool down for a bit and place it away from the wall so you can approach the backside of the refrigerator.
Now all you need to do is one by one clean all the coils, you can use a brush to remove the dirt and grime gathered on the coils. However, do not forget to vacuum as the residue left behind may cause the refrigerator to not function properly.
Now take a look at the compressor and see if there are any signs of damage. Take a careful look at the condenser fans as well to make sure that the fans do not have any obstruction and function properly. Clean out the vent and place everything back.
Turn the refrigerator on and listen for any buzzing noises. If all else is working fine and you have spotted that the condenser is the main element causing all the sounds.
Then call in an expert or call the helpline of the company to seek advice. A technician will be able to help you figure out which part is needed and will help replace it for you.
This all comes to show that buzzing noise in the refrigerator can be easily fixed by experimenting with the appliance.
Cleaning all the necessary assembly parts will help you pinpoint the problem area. This is further beneficial in being able to understand if the assistance of a professional is required or not.
However, when performing these kinds of tests make sure to wear proper protective gear that ensures that there is no chance of an electrician. Furthermore, try calling the helpline of the manufacturer to understand the problem better.
