Hello their, thanks for trying fixya, the issue with these type of tools is normally the ac motor, their are many diffident types used but yours in particular 120V, 50-60 Hz, AC, 1.15 amp double insulated motor. Operates from 5,000 to 30,000 RP, their is a electric motor that may have failed on you or the switch could burned out. this is possible when the contacts are shorted for to long become to hot and overload the small circuit used to control potential voltages to the motor, consider it like a variable pot switch.
a simple test here would be you can take the unit apart easily enough and unplug from wall, make sure you have no voltage from mains going in. when the unit is not plugged in get your trusty voltage ohm meter or vom
