I looked at the belt and it seems to be okay. There is a fair amount of black residue from the belt on the pulleys, but the belt seems to be okay. The tension on the belt also seems okay, but I'm not sure how tight it should normally be.
Are you suggesting I replace the lid switch? I'm curious why this would cause the timer to stop in a particular spot?
I'm not clear what you are telling me to do. Should I replace the lid switch and the belt?
