Check that the door is fully closed and the gasket is sealing all the way around. If it comes back, it needs a visit. ### What should I move first when my U-Line shows Temp Hi 6H+? Anything that spoils easily should go somewhere cold while the zone recovers. The zone has sat more than 10 degrees over its set point for six hours or more. Check that the door is shut and the gasket seals all the way around. ### What if Temp Hi 6H+ turns into Temp Hi 12H+ on my U-Line? That means the zone has stayed warm past twelve hours, so the problem is persisting. The message states the condition but not the cause. Contact U-Line Customer Care if it returns after the door check. --- **[Read on the site: U-Line refrigerator showing Temp Hi 6H+](https://refrigeratorrepair.center/error-codes/u-line-temp-hi-6h/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
