Today I had the exact same issue on the exact same fan. By going off your comment, I was able to get it going by following your procedure. I can’t thank you enough man. Just saved us potentially thousands of dollars.
+Richard Zamzow Just battled this. My motor was bad. Between to leads on the motor I was reading 4.7 ohms and about 10 ohms on the others( this is the 3 leads going into the motor itself ). Found burnt (black) windings in two places where the motor windings wrap around the plastic tabs on the end of the stator. I separated the windings where burnt together and re-checked the resistance and all showed 10.8 which is good. Insulated the burnt windings (varnished them), put the motor back together and it is running great at no cost! Yet????
