Temperature varies significantly between top and bottom shelves; some bottles are much warmer or colder than others.

Safety first: Unplug the unit before accessing the fan or interior panels.

Steps to improve temperature uniformity:

• 1. Check evaporator fan: Confirm that the internal fan runs when the compressor is on. Replace the "evaporator fan motor" if it is not operating.
• 2. Rearrange bottles: Avoid overpacking shelves. Leave space between bottles and do not block air vents at the back or sides.
• 3. Rotate stock: Place more temperature-sensitive bottles in the middle shelves where temperature is most stable.
• 4. Dual-zone models: Ensure the internal divider and seals between zones are intact and properly installed.
