Hello all,
last year I tried to start my old fan and it wasn't starting. Then I tried to rotate the fans by my hands with power on to the motor and I felt like there is some torque which is acting in the reverse direction (i.e trying to prevent the fan to rotate). I am not exactly sure whether it was some mechanical jamming or there is some electrical torque built up in a reverse direction. Then I turned off the power to the motor and I rotated the fans like 25-30 times in the correct direction ( I even can feel the torque but as I rotate more and more the torque decreases) and then I powered on the fan and it started spinning. The speed of the motor gradually went down and in like 2 hours it stopped.
Everyday I used to do the same thing, spin it for 25-30 times with power off and then it starts. But after few days it's completely dead.
Now this year, I tried to spin the motor and I didn't feel any opposing torque or jamming. But the fan is still dead i.e not starting on power supply. What could be wrong with the fan? Is it the condenser/capacitor?
