Flashing degree symbol / snaking charactersFlashing degree symbol / snaking characters questions

Why does my U-Line not cool?

In showroom mode only the control and cabinet lights work. The compressor and fans stay off, so the cabinet warms. Exit the mode and cooling begins again. Lights and display stay on, which makes it look like the unit works.

How do I leave showroom mode?

Hold COLDER and press LIGHT three times. Software 2.8 exits when the unit is unplugged. Cooling restarts after the mode ends. Exit takes only a few seconds.

What if the keys do not exit it?

If the flashing degree symbol stays after you try both methods, call us. We check the control, and you get the price in writing before work starts.
