Strange noises from Fridge Freezer

Last updated 10/08/2021 11:28


  • Fridge freezer emits strange noises; churning, clunking, clicking, popping, vibrating, running motor
  • The fridge is too noisy

Applies to

  • Freestanding/integrated fridge freezers
  • Wine coolers
  • Integrated fridges/freezers


1. Make sure the ventilation requirements are met. Refer to the installation instruction supplied with your appliance

All refrigeration appliances require ventilation to ensure correct operation. This is crucial in the case of integrated appliances, where vents are required for this purpose. Sometimes noises can occur because the appliance performance is affected due to insufficient ventilation

A minimum of 200cm2 of ventilation must be provided at both the top and the bottom of the cabinetry to allow correct airflow

2. Your appliance will make various sounds during normal operation including the following:

  • A faint gurgling and bubbling sound when the refrigerant is pumped through the coils or tubing.
  • A whirring sound and pulsating noise from the compressor when it is pumping.
  • Sudden cracking noise is caused by thermal dilation.
  • A faint click of the temperature regulator when the compressor switches on or off.

Please see the below diagram for examples of the noises that you may hear when the appliance is running:
