How to Fix a Fridge That Makes Noise: Common Causes and Solutions
A noisy fridge can be unsettling, but most sounds are normal or have simple fixes. This guide explains the most common fridge noises and what to do about each one.
Normal Fridge Sounds (Nothing to Worry About)
Humming or Whirring
A steady, low hum is the sound of the compressor running — completely normal. All fridges hum. If the hum is consistent and not very loud, there's nothing wrong.
Clicking
A click when the fridge turns on or off is the thermostat switching the compressor. Normal.
Gurgling or Bubbling
This is the sound of refrigerant flowing through the system. Completely normal, especially after the door has been opened.
Cracking or Popping
Fridges and freezers expand and contract slightly as temperatures change. These cracking sounds are normal and nothing to worry about.
Noises That Need Attention
Loud Vibrating or Rattling
Cause: The fridge is touching a wall or cabinet, or items on top of the fridge are vibrating.
Fix: Pull the fridge away from the wall, leaving at least 5cm clearance. Remove anything sitting on top of the fridge. Level the fridge using the adjustable feet at the base.
Buzzing or Humming That's Getting Louder
Cause: Could be a dirty condenser coil (reducing efficiency) or a faulty compressor.
Fix: Clean the condenser coils at the back or bottom of the fridge with a vacuum and brush. If the noise continues and the fridge isn't cooling properly, the compressor may need attention.
Ice Maker Noise (Loud Clunking or Thudding)
Cause: Ice being dropped into the ice bucket is normal. Louder clunking may mean ice has built up and is blocking the ice maker.
Fix: Defrost the ice maker by turning it off and removing any ice build-up.
Squealing or Chirping Fan Noise
Cause: A squealing fan usually means the evaporator fan blade is hitting ice build-up in the freezer, or the fan motor is wearing out.
Fix: Defrost the freezer completely. If the noise continues, the fan motor may need replacing.
Knocking or Banging Inside the Fridge
Cause: Items inside the fridge may be touching the fan. Or the fridge is not level.
Fix: Rearrange contents so nothing is touching the back wall or fan area. Level the fridge.
