How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before accessing the rear compartment.

Steps:

1. Access rear compartment: Remove the lower back panel to expose the compressor and condenser fan.
2. Identify noise source: Briefly plug in and listen carefully to determine if the noise comes from the fan or compressor. Unplug again before touching anything.
3. Inspect condenser fan: Check for debris (plastic, paper, dust) hitting the fan blade. Clean thoroughly.
4. Check fan blade and motor: Wiggle the blade; excessive play or wobble indicates worn bearings. Replace the condenser fan motor and blade if noisy.
5. Inspect compressor mounts: Ensure rubber grommets are intact and that copper lines are not touching the cabinet. Adjust as needed to reduce vibration.
