Wine cooler interior temperature fluctuates widely; some bottles are too warm while others are too cold.

Safety: Disconnect power before removing interior panels or touching the fan.

Steps:

• 1. Check loading pattern: Ensure bottles are not blocking rear or side air vents. Leave space between bottles for airflow.
• 2. Listen for fan operation: When the compressor runs, you should hear the evaporator fan. If not, access the fan behind the rear interior panel.
• 3. Inspect for ice: Look for frost or ice around the evaporator and fan. Manually defrost if necessary and investigate defrost system if ice returns quickly.
• 4. Test and replace fan: If the fan does not run or is noisy, test resistance and replace the evaporator fan motor if defective.
• 5. Check air ducts and flaps: On dual-zone models, ensure air diverter flaps move freely and are not obstructed.

Note: Stable temperature is critical for wine; resolving airflow issues will improve consistency across shelves.
