Freezer makes loud humming or buzzing noise from compressor area.

Safety first: Unplug the freezer before adjusting components near the compressor or fan.

Steps:

• Check compressor mounts: Inspect the rubber grommets under the compressor. Replace if cracked or missing to reduce vibration.
• Secure tubing: Gently bend refrigerant lines away from cabinet walls or each other if they are touching and vibrating. Do not kink or sharply bend the tubes.
• Fan inspection: Ensure the condenser fan (if fitted) is not rubbing against its housing. Adjust or replace the fan if damaged.
• Compressor condition: If the compressor itself is excessively loud or knocking, it may be failing. Continued operation is possible but efficiency and lifespan are reduced; replacement requires a refrigeration technician.
