It's not the motor, it's probably either a capacitor, or a relay. Take the cover off and smell it, if it smells burnt inside, the capacitor should be a black cylinder about 3" long x 1 1/5-2" across they are about $15. If it doesn't smell find the relay, and spray a little bit of wd40 inside to lube the internals. Try this and get back to me with a model#.
