How to Fix / Troubleshooting

Quick user actions:

Ensure the refrigerator is level front-to-back and side-to-side using the adjustable feet. Use a spirit level if available.
Check that the appliance is not touching walls or cabinets; leave a small gap to prevent vibration transfer.
Remove any items vibrating against the back or sides of the unit.

Fan inspection:

Unplug the unit and remove the rear lower cover to access the condenser fan. Tighten any loose mounting screws and clear debris.
Inside the freezer, remove the rear panel to access the evaporator fan if noise comes from inside. Check for ice hitting the blades and defrost if necessary.
If a fan motor is noisy even when clear of obstructions, replace the fan motor.
