It is not that absurd because most refrigerators when the door is closed tend to make some kind of noise that is considered weird. There could be many causes that are behind producing such noise that will be discussed in this blog as well as how to fix these noises. The noise produced is not always because of technical aberrations but there can be several reasons behind it by meticulously recognizing the noise. I will explain every possible reason behind the squealing, grinding, resetting, and banging sound created by fridges when the door is closed.
Important Point: “If you want to get rid of noise created by your refrigerator, you should have to know what the causes are and recognize which kind of noise your refrigerator is making.”
I have discussed several reasons behind the noise produced by refrigerators and the ways which can help fix this problem.
Malfunctioned Evaporator fan
If your refrigerator makes a noise that is like a loud humming, rattling or knocking sound, or squealing can be produced by malfunctions in the evaporator fan motor. If the voice does not generate it would cause the freezer to warm.
Ways to fix
It can be fixed by replacing the evaporator fan motor, if you don’t want to get disturbed by these noises anymore.
Obstructed Evaporator Fan
Another cause of noise generated by your refrigerator can be obstructed evaporator fan if you feel that the noise is kind of grinding something and it is extremely annoying. This is happening because various things obstructed the fan and lead to rubbing against them. The things can include dust particles, ice buildup, and food because of overloading.
Ways to fix
The method to fix this issue is to not overload your fridge as well as defrosting the ice mass is also effective.
Damaged Condenser Fan
Moreover, another main reason that can arise this issue can be an anomaly or malfunctioned condenser fan. It will make a noise that will indicate it is struggling to cool. It is the weird noise of grinding sound or rattling.
Ways to fix
The question is how to fix this technical anomaly, so the answer is that replace the condenser fan instantly if you want to get rid of this problem.
Unstable Fridge
If your refrigerator makes the noise of loud vibrating sound once it starts to run, there can be three reasons as far as possible, first is when your fridge stands on the unleveled ground, the second one is the possibility of wobbly items being placed in your fridge, and last but not least it can be happened because of tray in your refrigerator.
Ways to fix
If you want to fix this noise, you are supposed to find these reasons and act accordingly. For instance, you have to stabilize your fridge or maybe you can correctly position the items you have placed in it.
Ice Build-Up
Another main reason can be behind the weird sound is the accumulation of ice in the freezer that can make worse noise. The root cause most probably is the obstruction of the fan by ice mass and the noise will feel like grinding something or clattering.
Ways to fix
You may fix it by defrosting accumulated ice which can be easily done by using a hair dryer or another way is by unplugging the fridge which will allow it to defrost on its own.
Dirty Condenser
Furthermore, another cause of the grinding effect made by your refrigerator when you close it can be the filth accumulating on the fridge’s condenser. You can fix it by cleaning the fridge regularly and your condenser to get rid of accumulated dust. There is another suggestion; you can use a condenser cleaning brush to do it more effectively and in less time.
Faulty Door Hinge or Door Seal
Besides the above reasons, a significant reason can be the faulty door hinge or door seal. A squealing sound will be produced if your refrigerator is struggling with a broken door hinge. Additionally, if the door seal is malfunctioned, either loose or damaged will produce the same consequences.
Ways to fix
It can be fixed by replacing the door seal or the fridge door if it is faulty or damaged somehow.
Temperature Fluctuations
As well, temperature fluctuations can be a good reason for making weird noises coming from the closed refrigerator. If the temperature of the fridge is not normal, either abnormally low or abnormally high, it indicates that the refrigerator is not running smoothly and the reason is the malfunctioned compressor.
Ways to fix
If you want to fix this noise, you have to adjust the temperature correctly.
Poor Airflow (Lack of Sufficient Clearance)
When your refrigerator makes some noise like a rattling or knocking sound, it can be caused by the air vents that have been blocked by dust or food.
Ways to fix
It can be fixed by creating clearance around the refrigerator that should be 5 cm at least, and you are not supposed to overstuff food that can block the air vents consequently.
