INFORMATION
Winding resistance values above are given for reference. You should NOT be reading
a value in kΩ or a short‑circuit. Make sure that the propeller fan blade does NOT
rotate, as this could affect resistance measurements.
9
Set the Megger voltage to 500 V DC or 1000 V DC.
10
Measure the insulation resistance for the motor terminals. Measurements
between each phase and fan motor body (e.g. axle) MUST be >1000 MΩ.
Are the measured resistance values
correct?
Action
Yes
Perform a check of the main PCB, see
No
Replace the DC fan motor, see
