Freezer makes loud humming, buzzing, or rattling noises during operation

Safety first: Unplug the freezer before accessing fans or moving the unit.

• Level the appliance: Use a level to ensure the freezer is sitting flat. Adjust leveling legs as needed to prevent vibration.
• Inspect condenser fan: Remove the rear lower panel and check the condenser fan for debris or bent blades. Clear any obstructions and straighten blades carefully.
• Secure tubing: Look for refrigerant lines that are touching each other or the cabinet and vibrating. Gently bend them away or use foam sleeves or clips to isolate them.
• Check evaporator fan: If noise comes from inside the freezer, remove the interior rear panel and inspect the evaporator fan. Replace the fan motor if it wobbles, grinds, or has excessive play.
• Compressor mounts: Ensure the compressor mounting bolts or rubber grommets are intact. Replace damaged mounts to reduce noise.
