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

Safety: No electrical work is required; keep the unit plugged in only if you are not removing panels.

• Rearrange bottles: Ensure bottles are not touching each other or the cabinet walls. Use spacers if necessary.
• Secure shelves: Push shelves fully into their rails and confirm they are locked in place. Add felt pads where metal meets metal if needed.
• Check fan cover: If accessible, gently press on the rear interior panel or fan cover while the noise occurs. If it stops, tighten screws or add damping material.
