I hope someone can help me. I was given a Sears Radial Arm Saw that
does not work. The model number is 113.197750. When I turn it on, the
motor hums but does not turn. I turn the motor when it is on and it
turns freely but will not spin on its own.



That motor uses a centifical switch and a capacitor to run. Either one could
be bad. The capacitor may be the easist to just replace, any motor shop
should have one for less than $10. The centrifical switch may be more
diffecult as it requires some dissassemly of the motor.
