  Annette HumphreyAug 31, 2025
  If the Airwell Heat Pump compressor is overheating and not producing capacity, possible causes include an EEV problem, refrigerant leakage, or a blockage in either the indoor or outdoor coil. You should check the EEV and refrigeration system. Also, clean the filters and remove any blockage from the indoor coil. Clear any obstructions from the outdoor coil and prevent air bypass.

  If the power supply indicator (Red LED) on your Airwell Heat Pump doesn't light up, it indicates there's no power supply. Check the power supply. If the power supply is OK, check the display and display wiring. If those are OK, replace the controller.

  If the indoor fan of your Airwell Heat Pump doesn't start, but the louvers are open and the green LED is lit, there could be a few reasons: * If the unit is in heat mode, the coil might not be warm yet. Try changing to cool mode to test. * There might be a problem with the PCB or capacitor. Switch to high speed and check if the power supply to the motor is higher than 130VAC (for triack controlled motor) or higher than 220VAC for fixed speed motors. If it is, replace the capacitor. If not, replace the controller.

  If your Airwell Heat Pump unit isn't responding to the remote control, the remote control message may not be reaching the indoor unit. First, check the remote control batteries. If the batteries are fine, inspect the display and display wiring. If those are OK, replace the display PCB. If the unit still doesn't respond, replace the controller.
