A noisy fridge is annoying, and it can also leave you wondering whether something is about to fail. The good news is that many fridge noises can be quietened at home with a few simple steps, and the ones that cannot are usually easy to identify.
This is a practical, step-by-step guide. If you want to identify a specific sound first, read our guide to common fridge noises and what they mean.
How to Fix a Noisy Fridge: The Short Answer
Start with the simple fixes: level the fridge, pull it slightly away from the wall, rearrange items that touch each other, clean the condenser coils and fan, and make sure the drain pan is seated properly. If the noise is a squeal from the freezer, a grinding sound or repeated clicking with poor cooling, the fan motor or compressor needs a technician.
Step 1: Confirm the Noise Is Not Normal
A low hum, soft clicks when the compressor starts and stops, gurgling refrigerant and crackling during defrost are all normal. Noise usually rises for a while after the door has been open or after you add a lot of warm food. If the sound is louder, constant, harsh or new, keep going.
Step 2: Find Where the Sound Is Coming From
- Inside the freezer: usually the evaporator fan.
- Back of the fridge near the floor: condenser fan or compressor.
- Underneath: drain pan or levelling feet.
- Inside the fridge compartment: items rattling on shelves or door bins.
Opening the freezer door is a useful test. If the noise stops or changes, the evaporator fan is the likely source.
Step 3: Level and Stabilise the Fridge
An uneven fridge vibrates and rattles. Place a spirit level on top and adjust the front feet until the fridge is steady, with the front slightly higher than the back so the doors close on their own. Check that it is not rocking on an uneven tile or floorboard.
Step 4: Give the Fridge Some Space
A fridge touching a wall, cabinet or pipe can transfer vibration and make a normal hum sound much louder. Leave a small gap at the back and sides as the manual recommends. This also helps the fridge shed heat and run more efficiently.
Step 5: Rearrange the Contents
Bottles and jars that touch each other or the back wall can rattle when the compressor runs. Spread items out and make sure nothing is pressing against the rear panel or blocking the air vents.
Step 6: Clean the Condenser Coils and Fan
Switch the fridge off at the wall first. Pull it out carefully, then vacuum dust and lint from the coils and the condenser fan, which is usually near the compressor at the back or underneath. Dust makes the fan work harder and can cause a buzzing or rattling sound.

Step 7: Check the Drain Pan
The drain pan sits underneath the fridge. If it has shifted or is loose, it can rattle every time the compressor runs. Make sure it is seated properly.
Step 8: Check for Ice Around the Freezer Fan
If you hear grinding or scraping from the freezer and see heavy frost on the back wall, ice may be catching the evaporator fan blades. Defrosting the fridge fully can stop the noise for a while, but ice usually returns if the defrost system has failed. That needs a proper repair.
When to Stop and Call a Technician
Leave it to a professional if:
- the noise is a squeal or grind that returns after you have checked for ice
- the compressor clicks on and off and the fridge is warming up
- you hear knocking from the compressor while it runs
- there is a burning smell, scorch marks or the power keeps tripping
- the fix involves removing internal panels, fans or electrical parts
Fan motors, relays and control boards should be replaced by a qualified technician, and any work on the sealed refrigeration system requires an ARC licence.

Frequently Asked Questions
How do I stop my fridge from making noise?
Level the fridge, move it slightly away from the wall, rearrange items that are touching, clean the condenser coils and fan, and check the drain pan. If the noise continues, a fan motor or compressor component may need replacing.
Why is my fridge suddenly so loud?
A sudden increase in noise often comes from a worn fan motor, ice catching the evaporator fan, a dusty condenser fan or the fridge being moved out of level. If it is also warming up, book a technician.
Can I fix a noisy fridge fan myself?
You can clear dust and check for ice, but replacing fan motors involves removing panels and electrical connections. That work is best left to a qualified technician.
Does a noisy fridge mean it is about to break?
Not always. Many noises are harmless. A new, harsh or worsening noise, especially with rising temperatures, is worth having checked early.
