Index 1:
1.Indoor AC fan motor
Measure the resistance value of each winding by using the tester.
For the definite value of the resistance, refer to page61 and page64.
Index2:
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.Outdoor DC Fan Motor(control chip is in outdoor PCB)
NO.

1) Release the UVW connector. Measure the resistance of U-V, U-W, V-W. If the resistance is not
equal to each other, the fan motor must has problems and need to be replaced. Otherwise, go to
step 2.
2) Power on and when the unit is in standby, measure the voltage of pin4-5 in feedback signal
