Loud buzzing or humming noise from rear of refrigerator.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before accessing the rear compartment.
Steps:
- Remove rear panel: Expose the compressor and condenser fan area.
- Inspect fan: Check for insulation, zip ties, or debris contacting the fan blade. Clear any obstructions.
- Spin fan by hand: If it feels rough or wobbly, the motor bearings may be failing.
- Check compressor mounts: Ensure rubber grommets under the compressor are intact and that copper lines are not touching the cabinet and vibrating.
Corrective action: Replace a noisy condenser fan motor or damaged blade. If the compressor itself is excessively loud, consult a technician; compressor replacement is a sealed system repair.
