Found heater open which really doesn't make since because the dryer was drying clothes. Anyway, ordered and replaced heater. No change. Timer is still not advancing in the temperature mode but will advance in the timed mode but still will not shut off.
I pulled the dryer back out of it's closet and traced every wire that I could find. I found a part open that has orange wires on each side of it. I took the wiring diagram that you gave me, which I am very thankful for btw, and I assume that this part is a resistor. Part # 15 on the schematic. But, part # 15 on the parts breakdown is not the part that is on my dryer. Can you possible confirm that I'm heading in the right direction. Can I jump this part out?
