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 cooler

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.

01

Check the zone setting and confirm it was not lowered by mistake.

02

Measure the zone with a thermometer in a glass of water left for an hour.

03

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.

Questions
about Temp Lo 6H+.

Can I clear Temp Lo 6H+ myself?
Check the zone setting and confirm it was not lowered by mistake. If it comes back, it needs a visit.
Why would a U-Line wine zone get 10 degrees too cold?
Usually because cooling does not switch off when it should, often a control relay. A zone sensor reading warm can cause the same thing.
Can the cold hurt my bottles?
A zone set to 55°F running at 45°F slows aging rather than harming wine. Much colder than that risks pushed corks, so move bottles if it keeps dropping.
Is Temp Lo 12H+ more serious than 6H+?
It is the same condition lasting longer. Both mean the zone has not come back up on its own.

Back to your everyday

Still showing Temp Lo 6H+?

When you book, copy the code or the blink pattern as the display shows it, add the whole model number, and say whether the bottles still feel cool — a code gives the technician a head start.
