I have a forward reversible variable speed motor that is only working when it is dialed to no less than 4 and no more than 6 on the dial. Is this something that is fixable or is it a goner? Thanks!

This speed control is a very basic wire wound resistor which is swept by a spring loaded device. The wire wound surface is not broken because you are getting some voltage. Well it may be broken at the "6" point but unlikely. But it may be dirty. Most likely though is that the spring loaded device is not making contact either because it is worn away or that the spring is jammed or has lost its tension. You can take the bottom off the motor and check out these possibilities.
