Loud humming or buzzing noise from the rear of the wine cooler.

Safety: Unplug the cooler before touching moving parts.

• Level the unit: Adjust the front leveling feet so the cooler is stable and does not rock.
• Check compressor mounts: Access the rear and ensure the compressor mounting bolts and rubber grommets are intact and tight.
• Inspect condenser fan: Verify the fan blade is not rubbing against the shroud or wires. Bend or reposition parts as needed.
• Secure panels: Tighten any loose rear or side panels that may vibrate.
