Wine cooler makes loud humming or buzzing noises during operation.

Safety: Unplug the unit before adjusting internal components near the compressor.

• Level the appliance: Use a spirit level and adjust the front feet until the cooler is stable and does not rock.
• Check for contact points: At the rear, ensure copper tubes and the condenser are not touching the cabinet or each other in a way that can vibrate. Gently bend them away if needed, without kinking.
• Secure panels and shelves: Tighten any loose screws on interior panels and ensure shelves are properly seated.
• Compressor evaluation: If the noise is a deep, irregular knocking or grinding from the compressor itself, the compressor may be failing and should be assessed by a professional.
