Randy,
For the cost, it sure is worth the try. While that could be the problem, I kind of doubt it. The good thing is that the sealed compressor motor is not likely to be hurt because is can't draw much current at the high frequency even with the expected higher voltage.
I don't know which manufacturer your unit is, but most that I have had open had a cut-out in the little box on the side that is held closed by a wire clip. That cutout is both temperature and current sensitive. Some also have a manual reset on that sensor (makes sense in a roof top unit with ~87 screws to access). There is not a high likelihood that the pump (compressor) is damaged, but the surrounding devices sure could be.
Wishing you luck
Matt
