What to do if my Danfoss OPTYMA Control AK-RC 101 Control Panel shows a flashing temperature?

  Maria MeyerAug 1, 2025
  If the temperature shown on the display is flashing, it indicates a minimum or maximum temperature alarm. The temperature inside the cold room has exceeded the minimum or maximum temperature alarm setting. Check that the compressor is working properly. Also, the sensor might not be reading the temperature correctly, or the compressor start/stop control may not be functioning as expected.
