Wine Enthusiast wine cooler is making a loud rattling or vibrating noise during operation.

Safety: Unplug the unit before adjusting internal components. Be cautious of sharp metal edges.

• Level the unit: Use a bubble level and adjust the front leveling feet until the cooler is stable and does not rock.
• Check external contact points: Ensure the cabinet is not touching walls, cabinets, or other appliances that can amplify vibration.
• Secure compressor and tubing: Remove the rear panel and gently press on the compressor and refrigerant lines while the unit is running (use caution around live parts). If noise changes, add foam pads or clips to isolate vibrating lines and tighten compressor mounting bolts if loose.
• Inspect fans: Look for fan blades rubbing against shrouds or wires. Bend shrouds slightly or reroute wires to clear the blades. Replace any fan with worn bearings or wobble.

Persistent loud mechanical noise from the compressor itself may indicate internal compressor wear, which requires professional evaluation.
