1:Indoor or Outdoor DC Fan Motor(control chip is in 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 has problems and need to be replaced.
DC motor voltage input and output
NO. Color Signal Voltage
1 Red Vs/Vm 280V~380V
2 --- --- ---
3 Black GND 0V
4 White Vcc 14-17.5V
5 Yellow Vsp 0~5.6V
6 Blue FG 14-17.5V
2. Outdoor DC Fan Motor (control chip is in outdoor PCB)
Power on ,and check if the fan can run normally, if the fan can run normally, the PCB must
has problems and need to be replaced, If the fan can’t run normally, measure the
resistance of each two pins. If the resistance is not equal to each other, the fan motor must
have problems and need to be replaced, otherwise the PCB must has problems and need
to be replaced.
