How to Fix a Fridge Making Noise
Last updated: 30 September 2026
Level the fridge, clean the condenser coils, check the fan, and check the compressor.
Overview
A fridge making a loud noise can be annoying and may indicate a problem. This guide covers diagnosing and fixing common fridge noises.
Step-by-Step Fix
Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).
- First identify the type of noise. A humming noise is often the compressor or fan. A rattling noise may be loose parts or a fan blade hitting something. A clicking noise may indicate a faulty relay or start capacitor. Knowing the type of noise helps identify the source.
- Check that the fridge is level. An unlevel fridge can vibrate and make noise. Use a spirit level on top of the fridge. Adjust the feet at the bottom to level it. Ensure the fridge is not touching any walls or cabinets as this can cause vibration.
- Clean the condenser coils at the back or underneath the fridge. Dust and debris on the coils can cause the compressor to work harder and make more noise. Use a vacuum with a brush attachment to clean the coils carefully.
- Check the fan. There are usually two fans in a fridge one for the evaporator inside and one for the condenser outside. If the fan blade is hitting ice or debris it will make a noise. Remove any obstruction and check that the fan spins freely.
- Check for loose items on top of or inside the fridge. Items like bottles or containers can vibrate against each other. Move items around to see if the noise stops. Items on top of the fridge can also cause vibration.
- Check the compressor. The compressor is a black dome at the back of the fridge. It should make a soft hum when running. If the noise is very loud or the compressor is very hot there may be a fault. This requires a professional to repair.
- Check the drip tray. The drip tray is located under the fridge. If it is loose or vibrating it can make a noise. Reposition or secure the drip tray.
- If the noise persists after checking all of the above there may be a problem with the internal components. Contact a qualified appliance technician to diagnose and repair the fault.
- To prevent future noise problems keep the fridge clean. Clean the condenser coils every six to twelve months. Ensure the fridge is level and not touching walls. Do not overload the fridge.
- If the fridge is old and making loud noises it may be nearing the end of its life. Consider replacing it with a more energy efficient model. A new fridge will run more quietly and use less electricity.
Common Symptoms & Diagnostic Resolutions
Review the common error codes and operating symptoms below to quickly identify the root cause of the fault before ordering replacement parts.
| Symptom / Code | Likely Root Cause | Recommended Resolution |
|---|---|---|
| Loud humming | Dirty condenser coils or failing compressor | Clean the condenser coils. If the noise persists the compressor may be faulty and require a technician. |
| Clicking noise | Faulty relay or start capacitor | The relay or capacitor needs replacing. This is a job for a qualified appliance technician. |
| Rattling noise | Loose parts or fan blade obstruction | Check the fan for debris. Tighten any loose components. Check the drip tray. |
| Buzzing noise | Fridge not level or vibrating against wall | Level the fridge using the adjustable feet. Move it away from walls and cabinets. |
Frequently Asked Questions
Why is my fridge making a loud humming noise?
Dirty condenser coils or a failing compressor are the most common causes. Clean the coils first. If the noise persists the compressor may need professional attention.
Is a noisy fridge dangerous?
A noisy fridge can indicate a failing compressor which may need repair. It is not usually dangerous but the fault should be investigated. If the compressor fails the fridge will stop cooling.
How do I stop my fridge from vibrating?
Level the fridge using the adjustable feet. Move it away from walls and cabinets. Ensure items on top of the fridge are not causing vibration.
How often should I clean the condenser coils?
Clean the condenser coils every six to twelve months. Dusty coils cause the compressor to work harder which increases noise and energy consumption.
