# U-Line: The display works, the light works, and the unit will not cool

### What the appliance is actually doing

This is a mode, not a failure, and it is the most expensive misdiagnosis on this make. Showroom mode exists so a dealer can stand a unit on a floor and demonstrate it without running the refrigeration. The maker’s own description: the degree symbol will flash, the display will be lit and the interior light will function — and the unit will not cool. Compressor, fans, everything, off. It reads exactly like a dead sealed system, and it is two keys held for five seconds.

### Quoted rather than interpreted

> 
The ºF / ºC symbol will flash. Display will be lit and interior light will function. Unit will not cool. Repeat command to return to normal operation.

From CONTROL FUNCTION 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.

### What to do about it

- Look at the degree symbol. If it is flashing rather than steady, this is the answer and there is nothing wrong with the appliance.
- Hold the light key and the power key together for five seconds. The display flashes once and beeps, and the unit returns to normal operation. The same pair puts it back.
- If the symbol is steady and the unit still will not cool, this is not showroom mode. The 2000 Series manual’s next line is to interrupt power to the unit momentarily; after that it is a real diagnosis and worth a visit.
- Worth knowing when a unit is new or has just been moved. Floor models get sold, and a unit that arrives from a showroom arrives in showroom mode.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/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](tel:+13058512207) and describe what the display is doing before booking anything.

Before **u line refrigerator not cooling** becomes a sealed-system quote, this is the thing to rule out, and it costs nothing to rule out.
