Freezer making loud humming or buzzing noise from rear

Safety first: Unplug the freezer before touching any moving parts.

• Locate noise source: Listen at the rear to determine if the noise comes from the fan or compressor.
• Inspect condenser fan: Check for debris in the blades, bent blades, or contact with the shroud. Adjust or replace the fan as needed.
• Tighten mounts: Ensure the compressor mounting bolts and rubber grommets are secure and not excessively worn.
• Level the unit: Adjust the leveling feet so the freezer sits firmly on the floor without rocking.
• Compressor noise: If the compressor itself is loud and grinding, it may be failing. Continued operation is possible but efficiency and lifespan are reduced; consider technician evaluation.
