Index 1:
1. DC fan motor(control chip is inside fan motor)
Measure the resistance value of each winding by using the tester. If any resistance value is zero, the fan
motor must have problems and need to be replaced.

Index2:
1. 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.
