Wine cooler makes loud humming, rattling, or vibrating noises during operation.

Safety: Unplug the unit before adjusting internal components. Avoid contact with hot compressor or condenser.

Steps:

• Level the unit: Use a spirit level and adjust the front and rear feet until the cabinet is stable and level.
• Check rear components: Remove the rear panel and ensure the condenser fan, compressor, and copper tubing are not touching the cabinet walls. Add foam pads or clips where needed.
• Tighten panels: Tighten any loose screws on interior and exterior panels.
• Rearrange shelves: Ensure shelves are fully seated and bottles are not touching the cabinet walls or each other excessively.
• Compressor mounts: Inspect the rubber compressor mounts. Replace if hardened or broken.
