Loud humming, buzzing, or rattling noise during operation

Safety: Unplug the unit before adjusting internal components. Use caution when moving the appliance.

• Level the unit: Use a bubble level and adjust the front leveling legs so the cabinet is stable and slightly tilted back.
• Check for contact points: Remove the rear panel and look for refrigerant lines or wiring harnesses touching the cabinet and vibrating. Gently bend or pad them with foam to prevent contact.
• Inspect condenser fan: Ensure the fan blades are not hitting shrouds or wires. Replace the fan motor if it is noisy or wobbling.
• Secure shelves and bottles: Make sure shelves are fully seated and bottles are not touching the cabinet walls. Rearrange bottles to reduce rattling.
