Rattling or clinking noise inside the cabinet when the compressor or fan runs.

Steps to eliminate rattling:

• Rearrange bottles: Ensure bottles are not tightly packed against each other or the cabinet walls.
• Secure shelves: Check that shelves are fully inserted in their rails and not warped.
• Add damping: Use thin rubber pads or silicone bumpers between shelf supports and the cabinet to reduce vibration.
