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

Safety: Unplug the unit before accessing the rear compartment. Beware of hot compressor surfaces.

Steps:

• Level the appliance: Adjust the front and rear leveling feet so the cabinet is stable and does not rock.
• Inspect rear components: Remove the rear access panel and check that the condenser fan shroud and compressor mounting bolts are secure.
• Clear obstructions: Ensure the condenser fan blades are not contacting wires, insulation, or dust buildup. Reposition or secure any loose items.
• Add vibration pads: Place anti-vibration pads under the feet if the floor is uneven or resonant.
