Check that the door on the warm side is closed and sealing all the way around. If it comes back, it needs a visit. ### How warm is a zone when U-Line shows Temp Hi 6H+? At least 10 degrees above what you set. On a zone set to 55°F, that means 65°F or warmer for more than six hours. ### Only the right side of my U-Line dual-zone is warm. What does that suggest? The other side is cooling, so the problem is more likely in that zone’s door, airflow or fan than in the whole system. ### Should I wait for Temp Hi 12H+ before calling? No. Six hours is already long enough to act. Check the door first, then book a visit if the zone stays warm. --- **[Read on the site: U-Line Temp Hi 6H+: a wine zone has been warm for six hours](https://winecoolerrepair.center/error-codes/u-line-temp-hi-6h/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
