How to Fix / Troubleshooting
Safety: Unplug the refrigerator before reaching behind or under it.
Steps:
- Pull unit out: Move the refrigerator away from the wall to access the rear.
- Inspect condenser fan: Check if the fan blade is rubbing against wires, insulation, or dust buildup. Clean and reposition as needed.
- Check fan bearings: Spin the fan by hand; if it feels rough or wobbly, replace the condenser fan motor.
- Inspect compressor mounts: Ensure rubber mounts are intact and the compressor is not contacting the frame directly.
- Level the unit: Adjust leveling feet so the cabinet is stable and not vibrating against cabinets or walls.
