High-pitched whine or squeal from inside the cabinet when the unit is running.

Safety: Unplug the wine cooler before accessing the interior fan.

• Access fan: Remove shelves and the interior rear panel to expose the evaporator fan.
• Check for ice: Look for ice buildup around the fan. Defrost the unit fully if ice is present.
• Inspect blade: Ensure the fan blade is not bent and does not contact the shroud or wires. Reposition wiring and straighten the shroud if needed.
• Spin test: Spin the fan by hand. If it feels rough or noisy, replace the fan motor assembly.
• Reassemble: Refit the panel and shelves, restore power, and confirm the noise is resolved.
