How to Fix / Troubleshooting

Safety: Unplug the freezer before working at the rear or bottom.

Identify noise source: Pull the unit away from the wall and listen from the back while it is running to determine if the noise is from the fan or compressor area.
Access rear panel: Remove the lower rear cover to expose the condenser fan and compressor.
Inspect fan: Check if the fan blade is rubbing on wiring, tubing, or the shroud. Reposition wiring and straighten the shroud as needed.
Check fan bearings: Spin the fan by hand. If it feels rough or wobbly, replace the condenser fan motor.
Secure tubing: Look for copper lines touching each other or the cabinet. Add foam sleeves or clips to prevent vibration.
Compressor mounts: Inspect rubber grommets under the compressor. If cracked or missing, have them replaced by a technician.

If the compressor itself is excessively loud and vibrating, it may be failing internally; consult a refrigeration technician.

Freezer is noisy; loud humming, rattling, or buzzing from the back or bottom of the unit.
