What should you do if your fan stops and the motor continues to work? This might be a flywheel issue. Call a Pro that was highly-rated by your neighbors. Flywheel replacement can be cheap depending on your area.
Typical issues occur with the blades or the motor capacitor. A motor capacitor (dual run, run or start capacitor) is an electrical component. The ceiling fan repair rep, electrician or handyman service will simply unhook wires for the old one and install a new capacitor.
