What we can confirm
Code Nothing on the display, and the cabinet never reaches its set point, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.
The code
Nothing on the display, and the cabinet never reaches its set point
This is the most important thing on this page and the appliance will not tell you about it. The maker's own words: if a zone thermistor fails, the unit continues to cool in a backup mode — Self Preservation Mode — to preserve the integrity of the contents, and otherwise operates normally. On the 2000 Series that backup is a fixed cycle, ten minutes on and forty minutes off, regardless of what the cabinet actually needs. So a unit with a dead sensor hums, lights up, responds to every button, logs a number nobody can see, and simply never holds temperature.

What the appliance is actually doing
This is the most important thing on this page and the appliance will not tell you about it. The maker's own words: if a zone thermistor fails, the unit continues to cool in a backup mode — Self Preservation Mode — to preserve the integrity of the contents, and otherwise operates normally. On the 2000 Series that backup is a fixed cycle, ten minutes on and forty minutes off, regardless of what the cabinet actually needs. So a unit with a dead sensor hums, lights up, responds to every button, logs a number nobody can see, and simply never holds temperature.
Quoted rather than interpreted
If a zone thermistor(s) in the unit fails the unit will continue to cool in a backup mode (Self Preservation Mode) to preserve the integrity of the contents. The unit will otherwise operate normally. 2000 Series Self Preservation Mode: The unit will cycle on for 10 minutes then off for 40 minutes.
From Zone Thermistors, Troubleshooting Extended, in a User Guide & Service Manual downloaded from U-Line's own site. Nothing on this page is decoded beyond what that sentence says.
What to do about it
- Take the display out of the argument. Put a thermometer in a bottle of water inside the cabinet, leave it twenty-four hours without opening the door, and read that instead — it is the maker's own method and it is the only number that means anything here.
- Listen to the cycle. Ten minutes running and forty minutes silent, over and over, whatever the load, is the fingerprint of this mode on a 2000 Series unit.
- Have the error log read. The sensor error is in there as E1, E2, E5 or E6 — the appliance knows exactly what is wrong and has no way of saying so.
- This is the one to act on rather than live with. A backup mode is designed to protect what is inside the cabinet until a repair, not to be the way the appliance runs.
Where this goes next
The job this usually becomes is thermistor and sensor replacement, 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 refrigerator not cold enough, with nothing on the display and nothing obviously wrong, is this — and it is a sensor rather than a sealed system.
