Wine cooler makes loud humming or buzzing noise while running.

Safety first: Unplug the unit before tightening any components. Avoid contact with hot compressor surfaces.

Steps to reduce humming/buzzing:

• 1. Level the cabinet: Use a spirit level and adjust the front leveling legs so the cooler is stable and does not rock.
• 2. Check rear panel and grille: Ensure the rear cover and front grille are securely fastened and not vibrating against the frame.
• 3. Inspect compressor mounts: Remove the rear cover and verify that the rubber grommets on the compressor mounting bolts are intact and tight. Replace worn grommets.
• 4. Examine condenser fan: Check that the fan blades are not hitting the shroud or wiring. Tighten the fan motor mounting screws and reposition any nearby wires.
• 5. Add vibration pads: Place anti-vibration pads under the cooler feet if it sits on a hard surface that amplifies noise.
