Do you know where I can find [a wiring diagram].
Probably only from GE... if the one that should have been in or on the appliance when it left the factory is missing.
I have contacted GE over a week ago and they still haven't emailed me one.
Some things take time with GE although you might want to check with them again to make sure they can even provide a replacement. They are not always available.
