  If the indoor fan of your Airwell Air Conditioner doesn't start, first ensure the unit isn't in heat mode with a coil that's not yet warm; if so, switch to cool mode. Also, check if the outdoor unit is in the opposite mode and change the operation mode accordingly. Check power supply to motor is higher than 130VAC (for triack controlled motor) or higher than 220VAC for fixed speed motors, if OK replace capacitor, if not OK replace controller.
