Freezer makes loud humming or buzzing noise from the rear, louder than usual, but still cools.

Safety: Unplug the freezer before touching the compressor or fan. Components may be hot.

Steps to reduce humming/buzzing:

• 1. Level the appliance: Ensure the freezer is level and stable. Adjust feet so it does not rock.
• 2. Check for contact points: Look for copper pipes or the compressor shell touching the cabinet or back panel. Gently bend pipes slightly away to create clearance (do not kink).
• 3. Inspect compressor mounts: Check the rubber compressor mounting grommets. Replace if hardened or cracked.
• 4. Condenser fan (if present): Clean the fan blades and check for wobble or grinding noise. Replace the condenser fan motor if noisy.

Note: Some compressor noise is normal. Sudden changes or metallic knocking should be evaluated by a technician.
