Loud humming, buzzing, or rattling noise during operation.

Safety: Unplug the unit before tightening components or accessing fans.

Steps:

• Isolate noise source: Listen carefully to determine if noise comes from inside the cabinet, rear, or base.
• Check leveling: Ensure the wine cooler is level front-to-back and side-to-side using the adjustable feet.
• Secure shelves and bottles: Reposition bottles and ensure shelves are fully seated to prevent rattling.
• Inspect fans: Access evaporator and condenser fans. Check for wobbling blades or worn bearings. Replace noisy fan motors.
• Compressor and tubing: Verify that refrigerant lines are not touching each other or the cabinet. Gently reposition and add foam sleeves if needed.
