Need to get the whole model and serial # and go to the GE website and contact them for info. Most likely has to do with the jack plugs used or there may have been a jumper (usually is) to go across 2 of them which you switch around to change rotation. If that jumper is missing you are hooped. Best to contact GE. MOst I have seen have that jumper.Buying motors from ZBay or those places is risky and that one may turn out to be a boat anchor.
