What we can confirm
Code Temp Lo 6H+, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
Temp Lo 6H+
The zone has been ten degrees under its set point for more than six hours. On a wine cooler or a beverage center this is the notification that costs money: too cold is what freezes bottles and pushes corks. On a two-zone cabinet the notification carries (L) or (R) to say which zone it came from; the maker's own note is that single zone models do not use the left or right indicator at all. Unlike the E numbers on the rest of this make, this one is shown to you: the 3000 Series monitors its inputs continuously and puts the notification on the user interface rather than only into a service log.

On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About U-Line error code Temp Lo 6H+
What Temp Lo 6H+ means, in the maker's own words
The zone has been ten degrees under its set point for more than six hours. On a wine cooler or a beverage center this is the notification that costs money: too cold is what freezes bottles and pushes corks. On a two-zone cabinet the notification carries (L) or (R) to say which zone it came from; the maker's own note is that single zone models do not use the left or right indicator at all. Unlike the E numbers on the rest of this make, this one is shown to you: the 3000 Series monitors its inputs continuously and puts the notification on the user interface rather than only into a service log.
Quoted rather than interpreted
(L) (R) Temp Lo 6H+ — Left or right zone temperature -10 degrees under set point for over 6 hours. Inspect main control for proper relay operation.
From ERROR NOTIFICATION and the service diagnosis guide, 3000 Series User Guide, in a User Guide & Service Manual downloaded from U-Line's own site. Nothing on this page is decoded beyond what that sentence says.
Where this notification actually lives
On your display, which on this make is the exception rather than the rule. The 3000 Series does not use the E numbers at all: it watches its inputs continuously and writes the notification on the user interface in plain words, so there is no hidden log to open and no key to hold. Every other U-Line in this catalog does the opposite — it logs the number in memory and shows you nothing but the door. If you are reading a phrase rather than a number, this is the series you own.
What to do about it
- Check the set point before anything else. A cabinet set for beer and loaded with wine reads as an error and is a setting.
- The service guide goes to the control next: inspect the main control for proper relay operation. A relay welded closed leaves the compressor running whatever the sensor says.
- Then inspect the refrigeration system against the maker's own System Diagnosis Guide.
- On a two-zone cabinet note whether it says L or R. One cold zone beside one correct zone is a different problem from a cabinet that is cold throughout.
Where this goes next
The job this usually becomes is diagnostic visit, and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 851-2207 and describe what the display is doing before booking anything.
u line temp lo error names a notification the 3000 Series puts on the display itself, which is what makes it different from every other number this maker logs.
