How to troubleshoot a Swegon BlueBox Kappa Sky that doesn't start and the display is off?

  Lisa BonillaAug 15, 2025
  If your Swegon Chiller unit isn't starting and the display is off, it could be due to a lack of main voltage. First, ensure the main disconnect switch is in the 'ON' position. If it is on, check the power supply line for voltage. Another possibility is that there's no voltage to the auxiliary circuit. In this case, verify that the protective devices both before and after the transformer of the auxiliary circuit are intact. If a protective device has tripped, reset it after identifying and resolving the issue that caused it to trip.

  Miss Carolyn Walker DDSAug 18, 2025
  If you notice oil on the discharge of the safety valve of your Swegon Chiller, it could be due to the valve opening because the protective devices aren't working correctly or due to overtemperature. Check if the high pressure switches are functioning; if not, replace them. You may also need to replace the valve itself. If the issue is due to overtemperature, replace the valve and restore the charge.

Why is my Swegon BlueBox Kappa Sky making abnormal noises on the hydraulic pipes?
- H
  Heather SnowAug 21, 2025
  If your Swegon Chiller is making abnormal noises from the hydraulic pipes, it might be caused by the system pump operating outside its performance curve with an excessive water flow rate or by the presence of air in the system. If adjusting the pump control isn't possible, try partially closing the shut-off device on the delivery side until the nominal flow rate is restored. Also, check that the air valves are not shut off and vent the system to remove any trapped air.

What to do if the display is off on my Swegon Chiller but the unit is operating normally?
- J
  Jimmy MossAug 26, 2025
  If your Swegon Chiller unit is operating normally but the display is off, the connection between the display and the control might be disconnected, or the display itself may not be working. Try restoring the connection between the display and the control. If that doesn't work, you may need to replace the display.

  Brian PerezAug 28, 2025
  If your Swegon Chiller unit doesn't start, the display is on, it could be due to a lack of 230V auxiliary power supply. Check that the secondary circuit of the 230V transformer is intact and that the protective devices downline of the 230V transformer are also intact. Verify that the phase sequence is correct and the phase sequence relay is working properly.

  nicholas27Sep 1, 2025
  If your Swegon Chiller is producing abnormal noises due to vibrations, it could be because the unit's weight isn't evenly distributed on the base. To fix this, adjust the height of the anti-vibration mounts to correct the weight distribution.

What if my Swegon BlueBox Kappa Sky Chiller won't start, the display is off, the control is powered, but LEDs aren't flashing?
- B
  Brandi ChandlerSep 7, 2025
  If your Swegon Chiller unit does not start, the display is off, and the control is powered correctly but the LEDs are not flashing, the control itself might not be working. In this case, you should replace the control.

Why is my Swegon Chiller pump leaking water on the first start-up?
- J
  Julia GarzaSep 12, 2025
  If you're experiencing water leaks from the pump of your Swegon Chiller on its first start-up, it's likely due to the mechanical seal bedding in. To resolve this, pressurize the pump body two or three times by closing and opening the delivery valve to correctly bed in the seal.
