Why doesn't the indoor fan start on my Airwell SX 30 DCI Heat Pump?

  If the Airwell Heat Pump indoor fan doesn't start, but the louvers are open and the Green LED is ON, there could be several reasons: * The unit is in heat mode and the coil is not yet warm: Change to cool mode. * The outdoor unit is in the opposite mode: Change the operation mode. * There's a problem with the controller or capacitor: Change to high speed and check the power supply to the motor. If the power supply is OK, 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.

  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.
