What Temp Hi 12H+
actually means.
Temp Hi 12H+ is the second stage of the same U-Line 3000 Series warm alarm. The zone has now been 10 degrees or more over its set point for longer than twelve hours, so the door, the evaporator fan and the refrigeration system all need to be checked.

What to do when Temp Hi 12H+ shows on the wine coolerKind of codeTemperature and alarms
The cooler read a zone well away from its setting and raised an alarm, sometimes showing the warmest figure it reached while the house was empty. The reason may be as small as a door left resting on a bottle neck or a long outage, or as serious as cooling that has stopped. Keep the glass door shut and feel a bottle in the middle of the rack before doing anything else; the alarm is a warning about the wine, not a diagnosis.
