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.
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.
