sparky,
is it a GE360CR? or in that family? We had a similar problem with a 360. Worked fine for about 10-12 yrs, then started to burn up control wires and coils. We actually found several cracks on the magnet and a few other places on the main contactor. It seems that someone had replaced the on of switch with a standard 3 way (leaving continuous power to either the on or off contactor.) that and the daily pounding of drawing in that load, finally did it in. We replaced the unit with the newer model (much smaller and lighter)
