I have a Nordic Track C1800 model number NTL99020, my belt drive quit working. I took the cover off to see if I broke a belt and I did not. However I did find a fairly large water bug sitting on the MC 2000 PWM motor controller that looked as though it had be fried. When I removed the bug a green light came on on the board and then my ground fault plug kicked out. Did I blow the board or is there another possible problem?
