Wine cooler interior temperature fluctuates widely; some areas are much warmer or colder than others.

Safety: Unplug the unit before removing interior panels or touching the fan.

Steps to improve temperature uniformity:

• Check loading pattern: Avoid pushing bottles directly against the rear wall or blocking vents. Leave space between bottles for air circulation.
• Verify fan operation: With the door closed and unit running, listen for the evaporator fan. If silent, unplug and inspect the fan behind the rear interior panel.
• Remove frost buildup: If the evaporator is iced over, fully defrost the unit (unplug, door open) until all ice melts. Check that the defrost system is functioning if frost returns quickly.
• Inspect air ducts and baffles: Ensure any plastic air guides or ducts are properly seated and not broken or blocked.
• Replace faulty fan: If the evaporator fan motor is not running or is noisy, replace it with a Haier-compatible motor.

Result: Proper airflow and loading should reduce temperature swings and hot/cold spots inside the cabinet.
