Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before working near moving parts.
Fan inspection:
- Remove the rear lower access panel.
- Check the condenser fan for dust buildup, cable ties, or debris contacting the blades.
- Spin the fan by hand; if it feels rough or wobbly, the motor may be failing.
Compressor and tubing:
- Inspect copper refrigerant lines for contact with the cabinet or each other; gently bend them away to prevent rattling.
- Check compressor mounting grommets; if they are cracked or missing, replace them.
Repair: Replace a noisy condenser fan motor or damaged fan blade. Persistent loud compressor noise may indicate internal wear and should be evaluated by a technician.
