Bionaire btr4002 tower. Was extremely dirty inside tons of chow hair. Cleaned everything like new. Squirrel cage will spin by hand not on its own power. Im guessing the start run capacitor is defective. Any idea where to buy a replacement cap?
The capacitor winding in the motor presets rotation direction. Without the capacitor, the motor will not know which direction to rotate. With a bad capacitor,or with no capacitor connected to a capacitor motor, turning the motor shaft by hand will cause the motor to rotate at operating speed in the direction manualy spun, so, the motor can rotate either way once started by hand. This proves a bad capacitor. If the motor just sits dead while energyzed, then the motor is open electricaly, usualy a thermofuse embeded into a winding goes out.
