What to do if my Airwell Heat Pump responds to the remote but the green LED doesn't light up?
If your Airwell Heat Pump responds to the remote control message but the Operate indicator (Green LED) does not light up, there is a problem with display PCB. Replace display PCB. If still not OK replace controller.
Why is my Airwell KXL DCI blowing air but not cooling or heating?
If your Airwell Heat Pump's indoor and outdoor fans are working, but there's no cooling or heating, the overload safety device on the compressor may have cut out because of low voltage or high temperature. Also, the compressor run capacitor may be faulty, or the compressor windings may be shorted. Try switching off the power and trying again after one hour, and check for proper voltage. If the problem persists, consider replacing the compressor capacitor or the compressor.
Why is there only a limited air supply from my Airwell KXL DCI Heat Pump?
A limited air supply from your Airwell Heat Pump, especially if accompanied by a whistling noise and ice formation on the indoor unit coil in cooling mode, suggests a lack of refrigerant. You should charge the unit after localizing the leak.
What to do if my Airwell KXL DCI Heat Pump doesn't respond to the remote control?
If your Airwell Heat Pump isn't responding to the remote, first check the remote control batteries. If the batteries are OK, inspect the display and display wiring. If these are okay, replace the display PCB. If the problem remains, replace the controller.
Why is my Airwell Heat Pump only blowing air and not cooling or heating?
If your Airwell Heat Pump is only blowing air and not cooling or heating, it could be due to a faulty outdoor fan motor or another fault that caused the compressor overload protection to cut out. Remove any obstructions from the outdoor fan. If the issue continues, replace the PCB.
Why is my Airwell Heat Pump not cooling or heating even though all components seem to be working?
If all components of your Airwell Heat Pump are operating properly but there's no cooling or heating, it's likely due to a refrigerant leak. Check the refrigeration system.
What should I do if the red LED power indicator on my Airwell KXL DCI doesn't light up?
If the red LED power indicator doesn't light up, check the power supply. If the power supply is OK, check the display and display wiring. If those are OK, replace the controller.
What to do if the compressor is running but the outdoor fan isn't working on my Airwell Heat Pump?
If the compressor is running but the outdoor fan isn't working, there could be a problem with the outdoor electronics or the outdoor fan itself. Check the outdoor fan motor according to the procedure in section 13.5.3 below, if not OK replace controller.
Why is my Airwell KXL DCI operating in the wrong mode?
If your Airwell Heat Pump is working in the wrong mode (cooling instead of heating, or vice versa), it could be due to electronics or a power connection issue to the RV. Check the RV power connections. If these are OK, check the RV operation with a direct 230VAC power supply. If that’s OK, replace the outdoor controller.
Why is only the indoor fan working on my Airwell KXL DCI Heat Pump?
If only the indoor fan is working on your Airwell Heat Pump, the run capacitor of the outdoor fan motor may be faulty, or the windings of the outdoor fan might be shorted. Replace the capacitor or replace the motor.
