Refrigerator Making Noise? Causes, Diagnosis, and Repair Solutions

Evaporator Fan Motor Issues

If you hear a loud humming or squealing from the freezer, the evaporator fan-motor may be on its way out. This fan is blowing cold air, worn-out bearings can make a lot of noise.

Condenser Fan Problems

The condenser fan is located at the end of the fridge, where your compressor is located. A rattling or buzzing noise can be the result of dust buildup or a malfunctioning motor.

Compressor Malfunction

The compressor may be struggling if you hear a loud clicking or knocking sound. This seems to be the ultimate component, and this should be checked by a mechanic.

Water Inlet Valve Is Loose or Malfunctioning

If your fridge has a water dispenser, or an ice maker, a malfunctioning inlet valve can make a loud buzzing noise while it fills.

Defrost Drain That Is Clogged Or Not Working

A gurgling sound might indicate water is catching because a defrost drain is blocked. Which can potentially lead to ice build up and improper drainage.

Vibration Due to Unbalanced Placement

An unleveled refrigerator may vibrate against the floor or wall. Leveling is done properly to avoid unwanted noise.

How to Identify Refrigerator Noise

If your refrigerator is making strange sounds, here’s how to track down the source:

Locate the Sound

Back of the Fridge: Probably a problem with the condenser fan or compressor.

Evaporator Fan Motor: Inside the Freezer

Bottom of the Fridge: The noise could be due to a clogged drain pan or water valve.

Check for Obstructions

Freezing might be an option if the noise problem isn’t too bad, so inspect the fan blades and condenser coils for dirt or debris that might be affecting operation.

Test the Leveling

Set your refrigerator legs so that it is level with the floor to minimize vibrations.

Listen for Cycling Sounds

A normal refrigerator turns on and off, but continuous loud noises can indicate a failing part.

How to Fix a Noisy Refrigerator

-Clean the Condenser Coils

Accumulation of dust can strain the compressor, creating noise. Clean through them with a vacuum or coil brush.

-Replace Faulty Fan Motors

And if a fan motor is noisy, a genuine replacement will last longer and run quieter.

-Unclog the Defrost Drain

Run hot water through the drain to remove any blockages and prevent blockage.

Repair or Replace the Compressor

If your compressor is making noise, it is calling for service or replacement. This is a complicated task to be approached by professionals.

-Secure or Replace the Water Inlet Valve

If your fridge is buzzing when dispensing water or making ice, the inlet valve needs to be tightened or replaced.
