Freezer making loud buzzing or humming noise, louder than usual.

Safety: Unplug the freezer before adjusting components at the rear.

• Level the appliance: Use a spirit level and adjust the front feet so the freezer is stable and does not rock.
• Check compressor mounts: Inspect the compressor mounting grommets. Replace if perished or missing, and ensure the compressor is not touching the cabinet directly.
• Secure condenser tubing: Gently bend or pad any copper tubes that are vibrating against the cabinet or each other. Use foam pads or clips as needed.
• Tighten panels: Tighten screws on the rear cover and any loose internal panels or baskets that may rattle.
