Wine cooler makes loud humming or buzzing noise from the back.

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

Steps to reduce noise:

• Level the unit: Use a spirit level and adjust the front leveling feet so the cabinet is stable and does not rock.
• Tighten panels: Check and tighten screws on the rear service panel and base frame.
• Inspect condenser tubing: Gently bend any copper tubes that are touching the cabinet or each other to create a small clearance. Do this carefully to avoid kinking.
• Check compressor mounts: Ensure rubber grommets under the compressor are intact. Replace worn grommets to isolate vibration.
