Most fridge freezers make some noise. Gentle humming, soft clicks, and occasional whirs are normal. What is not normal is loud banging, grinding, screeching, or rattling that keeps getting worse.

Unusual sounds are one of the earliest warning signs that a component is struggling.

Why noises should not be ignored

Every moving part in a fridge freezer has a purpose. When one of them begins to fail, friction increases, balance is lost, or airflow becomes restricted. These changes produce sound.

Ignoring these noises can allow small faults to turn into major breakdowns.

What different sounds usually mean

Buzzing or vibrating

This often comes from the compressor or condenser fan. It may also be caused by the appliance touching a wall or cabinet.

Minor adjustments or fan repairs typically cost £50 to £150.

Clicking

Clicking sounds usually come from the relay trying to start the compressor. If the compressor cannot start, the relay clicks repeatedly.

This can indicate electrical faults or compressor failure.

Repairs range from £80 to £300 depending on the cause.

Grinding or scraping

These sounds often come from fan blades hitting ice buildup or worn motor bearings.

This should be addressed quickly before the fan motor burns out.

Fan repairs usually cost £80 to £200.

Knocking or thumping

These sounds may come from loose internal components or refrigerant movement. While some gurgling is normal, loud knocking is not.

When noise becomes a serious issue

  • Noise becomes louder over time
  • Cooling performance drops
  • Sound is constant rather than occasional
  • Unit vibrates strongly
