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 connector. If the value is not 5V, change the PCB. Otherwise, go to step 3.
3) Rotate the fan by hand, measure the voltage of pin1-5, pin 2-5 and pin 3-5 in feedback
signal connector. If any voltage is not positive voltage fluctuation, the fan motor must
has problems and need to be replaced.
