Unit vibrates or makes noise only when certain shelves are loaded.

Safety: No electrical work required; handle bottles carefully.

Steps:

• 1. Reposition bottles: Ensure bottles are not touching the back wall or each other too tightly.
• 2. Seat shelves fully: Push shelves completely into their rails until they lock or rest firmly.
• 3. Add padding: Use thin silicone or cork pads between shelf and rail if minor rattling persists.
• 4. Test with different load: Remove and reload shelves to identify specific bottles or arrangements causing resonance.
