# U-Line: The display is showing a plain number between 1 and 16, or 99

### What the appliance is actually doing

Not an error at all. The maker’s own row: a factory test mode may be enabled; adjust the temperature to 99 and press the light icon. What is showing is the board’s programmed model number or a test value, not a code — which is why looking it up as an error code finds nothing anywhere.

### Quoted rather than interpreted

> 
Digital Display Shows 1-16 or 99. A factory test mode may be enabled. Adjust the temperature to 99 and press the LIGHT icon.

From Troubleshooting, 2000 Series manuals, 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

- Read the number and compare it against the model list in the manual. Every U-Line board carries a two-digit model number, and 7, 9, 11, 15, 23, 25, 37 and the rest each stand for a specific machine.
- Follow the maker’s own instruction: set the temperature to 99 and press the light icon.
- If it comes back, the board may be programmed to the wrong model, which matters for more than the display — defrost intervals and fan delays are set by that number.
- This is a good reason not to accept a replacement control board without asking whether it was programmed to your model afterwards.

### Where this goes next

The job this usually becomes is [control board and display repair](/services/control-board-and-display-repair/), 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](tel:+13058512207) and describe what the display is doing before booking anything.

Some of the people searching **u line error code 11** are looking at a board’s model number rather than an error, and eleven is a real entry in that list.
