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

Safety first: Unplug the unit before touching the compressor or fan area.

• Level the unit: Adjust the front and rear leveling feet so the cooler is stable and does not rock.
• Access rear compartment: Remove the rear lower panel to inspect the compressor and condenser fan.
• Check fan: Look for debris in the fan blades or shroud. Clean thoroughly and ensure the blades spin freely without contacting anything.
• Compressor mounts: Ensure the rubber grommets and mounting bolts for the compressor are intact and snug, but not overtightened.
• Secure tubing: Gently bend any vibrating refrigerant lines away from cabinet walls or each other, adding foam sleeves if necessary.
