1: Indoor AC fan motor
Power on and set the unit running in fan mode at high fan speed. After running for 15 seconds, measure the
voltage of pin1 and pin2. If the value of the voltage is less than 100V(208~240V power supply)or 50V(115V
power supply), the PCB must have problems and need to be replaced.
2. Indoor DC fan motor(control chip is inside fan motor)
Power on and when the unit is in standby, measure the voltage of pin1-pin3, pin4-pin3 in fan motor
connector. If the value of the voltage is not in the range showing in below table, the PCB must have
problems and need to be replaced.
