Cause Of A Refrigerator Making Loud Noise

My Refrigerator Making A Loud Noise

What is the reason for the loud noise of the refrigerator? Does the loud noise of your refrigerator bother you? Are you looking for a way to solve this problem? In this article, we will show you all the reasons for this problem and how to solve them. Stay tuned to the RepairLand website.

Cause of loud noise in the refrigerator

  • Refrigerator fans failure
  • Motor or compressor noise
  • Refrigerator gas
  • Defrost mode
  • The noise of a refrigerator ice maker

Refrigerator fans failure

Refrigerator fans mean the following fans:

  • Motor fan or compressor
  • Condenser fan
  • Refrigerator evaporator fan

Motor fan or compressor

Next to the motor or compressor of the refrigerator, there is a fan that is responsible for cooling the motor. This fan does not break by itself and only its motor is defective. We recommend lubricating it when the noise is from the motor fan. First open the blades and lubricate the fan properly.

Condenser fan

The condenser is located behind the refrigerator. In side-by-side models, the condenser is hidden behind a refrigerator by a cover. The condenser is the same network of black pipes behind the refrigerator. Which is responsible for cooling the refrigerator gas inside the refrigerator.

When the refrigerator starts, the condenser fan turns on and cools the condenser. If the fan has a problem, it will cause loud noise. To solve the problem, the fan must be replaced.

Refrigerator evaporator fan

Inside the refrigerator there is a fan that transmits cold to all parts of the refrigerator. This fan is called an evaporator fan. This fan is located behind the refrigerator wall and cannot be seen until the refrigerator cover is opened.

The noise of the evaporator fan is like something hitting the body of the refrigerator or making a croaking noise. This noise is heard when the refrigerator motor is running and the cold is transferred to the refrigerator.

Also, if the defrost components have a problem and the evaporator freezes, the fan will hit the ice cubes and make a lot of noise. To solve the problem, the refrigerator cover must be opened to check and solve the problem.

Motor or compressor noise

In three modes, the motor or compressor of the refrigerator produces noise:

  • The noise is from the motor itself
  • The noise is from the screws holding the motor to the body of the refrigerator
  • There is a problem with the starter relay

Motor or compressor noise

The noise is from the motor itself

The refrigerator motor normally runs for up to 10 years without any problems. This depends on the brand of motor or compressor. In 99% of cases, it is necessary to replace the motor when the noise is from inside the motor or compressor.

The noise is from the screws holding the motor to the body of the refrigerator

The refrigerator motor or compressor is tightened by special screws to its bases on the refrigerator body. In some cases, the motor stiffener base may be broken.

Or the screws may be loose. In this case, it causes vibration when the motor is running. This vibration causes loud noise in the refrigerator motor.

There is a problem with the starter relay

If your refrigerator has a knocking sound, it means that the starter relay cannot connect the coils and this noise can be heard. In the simplest case, changing the motor starter relay solves the problem.

Refrigerator gas

If the noise of your refrigerator is like the sound of dust inside an iron pipe or the sound of the wind or howling, it is related to the gas of the device.

If the condenser tubes are worn out and something has gone inside the tubes in any way, a noise can be heard by transferring the gas inside the condenser and the refrigerator motor.

To solve the problem, it is necessary to wash all the gas paths and recharge the refrigerator.

Defrost mode

When the refrigerator is in the defrost mode, the sound of ice breaking or the sound of water splashing can be heard from inside the refrigerator. At first glance, this noise may be disturbing. But it is the sound of the element or heater that is turned on and is melting the evaporator ice.

This is not a problem and may occur once or twice in 24 hours (depending on the refrigerator model). Of course, if the noise is too loud and bothers you, this should also be investigated.

The noise of a refrigerator ice maker

In refrigerators that have an ice maker, the ice maker may have a problem and cause an annoying noise. This noise can only be heard from the ice maker and is inside the refrigerator.

The ice maker noise is mostly due to the motor or lever. To solve the problem, you need to get help from a technician to repair your ice maker, or you can temporarily turn off the ice maker to fix the problem.
