U-Line Bar Refrigerator Flashing Degree Symbol: Showroom Mode

A flashing degree symbol on a U-Line display means Showroom Mode is on. Only the control and cabinet lights work, and the compressor and fans do not run. To exit on the BEV or 2218 control, hold the light key and the power key for 5 seconds.

What does U-Line Flashing degree symbol / snaking characters mean?

Showroom Mode is for display units on a sales floor. In this mode the lights come on, so the cabinet looks alive, but the compressor and fans are off, so nothing cools. A flashing degree symbol tells you it is switched on. People often mistake it for a cooling failure because the cabinet is warm and the display looks normal. The manual says plainly that it is not a malfunction. On the BEV and 2218 controls you exit by holding the light key and the power key together for 5 seconds. The 2000 Series Wine Captain guide gives a different sequence: hold the COOLER icon, then press LIGHT three times within five seconds. The Echelon 2000 and 2010 entry sequence differs again, and the manual lists a related Troubleshooting heading, Digital Display Functions But Unit Does Not Cool.

Affected models and control systems

U-Line models U-1215BEVS-00A and U-2218RS-00A, plus the 2000 Series Wine Captain guide (30267). The exit sequence differs between the BEV and 2218 control and the 2000 Series.

Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.

  2. On a 2000 Series unit, hold the COOLER icon and press LIGHT three times within five seconds.
  3. Wait several minutes and listen for the compressor and fans to start.
  4. If the unit still does not cool, note the model and what the display shows.

How a technician diagnoses Flashing degree symbol / snaking characters

  1. Identify the model and control type to choose the correct exit sequence.
  2. Exit Showroom Mode and confirm the compressor and fans start.
  3. Check the set point and ambient conditions.
  4. Allow the cabinet to pull down and measure the temperature.
  5. If it still will not cool, test the compressor start circuit and fans.
! Leave this to a technician
  • Cooling tests involve the sealed refrigeration system and live compressor circuits.
  • If it is not Showroom Mode, finding why the unit does not cool takes refrigeration instruments.

Flashing degree symbol / snaking charactersQuestions about U-Line Flashing degree symbol / snaking characters
Is the flashing degree symbol a failure?

No. It means Showroom Mode, which turns cooling off on purpose.

How long before the unit cools after exiting?

The compressor should start soon after exit, and the cabinet then needs time to pull down.

The key sequence does nothing. Why?

The sequence differs by control. The 2000 Series uses the COOLER icon and LIGHT presses.
