Wine cooler makes loud humming or buzzing noises during operation.

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

• Level the appliance: Use a spirit level and adjust the front leveling feet until the cabinet is stable and does not rock.
• Check for contact points: At the rear, ensure copper tubes and the compressor are not touching the cabinet walls. Gently bend tubing away and insert foam pads where needed.
• Tighten panels and shelves: Ensure all interior panels, shelf supports, and bottle racks are firmly seated and not rattling.
• Inspect condenser fan: If the noise comes from the fan area, check for debris in the blades and test the motor. Replace the fan motor if bearings are noisy.
