Freezer making loud buzzing or humming noise from rear

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

• Access rear compartment: Remove the lower rear panel to expose the compressor and condenser fan.
• Identify noise source: Spin the condenser fan by hand; if it feels rough or wobbly, replace the fan motor. Check that the blade is not rubbing on the shroud.
• Clean debris: Remove any zip ties, insulation, or debris contacting the fan or compressor.
• Check compressor mounts: Ensure rubber grommets under the compressor are intact. Replace if hardened or missing to reduce vibration.
• Compressor noise: If the compressor itself is loud and grinding, it may be failing. Operation can continue until cooling is affected, but plan for professional replacement.
