U-Line Wine Storage Temp Hi 12H+ Error Code

Temp Hi 12H+ tells you one zone of the cabinet has been warmer than it should be for a long stretch.

The definition

The left or right zone temperature is 10°F (5°C) above the set point for over 12 hours. You may see it as L Temp Hi 12H+ or R Temp Hi 12H+. It applies to the U-3036BVWCS-00B and to DWR and ZWC units, where L is the top zone or drawer and R the bottom.

Owner checks

Verify the door is closed and sealing, and contact Customer Care if the message persists. The manual also lists what affects internal temperatures: the temperature setting, the ambient temperature where the unit is installed, direct sunlight or a nearby heat source, the number of door openings and the time the door stays open, and the time the internal light is on. An obstructed front grille or a dirty condenser coil matter too, so make sure nothing blocks the grille at the bottom of the unit and the coil is free of dirt or lint.

What a technician checks

If excessive frost is also noted, the door and gasket seal and alignment are inspected, along with evaporator fan operation and the refrigeration system.

Related codes
