What Temp Lo 6H+
actually means.
Temp Lo 6H+ and Temp Lo 12H+ are the U-Line 3000 Series cold alarms. The zone has been at least 10 degrees under its set point for six or twelve hours. The service table points first at the main control’s relays, which may be keeping the cooling on, and then at the refrigeration system.

What to do when Temp Lo 6H+ 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.

Before you book,
in this order.
Each step comes from U-Line's own guidance for Temp Lo 6H+ on its wine coolers. Follow it to the end: the last card says whether this is a visit.
Check the zone setting and confirm it was not lowered by mistake.
Measure the zone with a thermometer in a glass of water left for an hour.
If it stays cold, move bottles out of that zone and book a visit.

What not to do
Temp Lo is not a door alert, even though U-Line’s owner advice starts with the door. A sensor that has failed outright shows Zone T Open or Zone T Short instead.
