Wine cooler emits a rattling or clicking noise from inside the cabinet.

Safety: No electrical work is required for basic checks. Unplug the unit if removing internal panels.

Steps:

• Reposition bottles: Ensure bottles are not touching the cabinet walls or each other tightly. Add soft spacers if necessary.
• Secure shelves: Confirm that all shelves or racks are fully seated in their supports and not warped.
• Check internal panels: Gently press on the rear and side panels inside the cabinet while the unit is running to see if the noise changes. Tighten any loose screws.
• Inspect fan area: Remove the internal rear panel and check that the fan blades are not contacting wires or plastic. Re-route wires and secure with clips.

Tip: Run the cooler briefly with shelves removed to isolate whether the noise is from the racks or internal components.
