The "on" light won't turn off even when all range

The dial on your iron is either stuck or broken.

I need help! My son mx650 is charged, but won’t run. Put weight on it won’t move but lift rear tire off ground and runs full throttle

your exhaust is clogged

maybe it needs to be cleaned, use some dawn and water on a rag and rub around the dail .

The burner is not level ,or you need to adjust the air flow on the end of the burner.

From the manual: The main oven and companion oven are equipped with heavy-duty, porcelain - coated racks which are designed to remain in the oven during the self-clean cycle.
So they have nothing to do with your problem. From what you describe it appears that as the thermostat button is turned it either simply powers down the oven because the command wire for the clean cycle is disconnected or it trips some kind of overheat safety that is functioning incorrectly.
The oven will have to be extracted from its place, its back removed to access the thermostat button (and its wirings) and the control board which will have to be tested. This isn't the simplest of jobs so if you have never done something like this before then you will have to call a pro. The parts won't cost much (less than $100) but the labor will so shop for the most affordable one.

Replace the control with a Ranco A12-1560

There is a transformer in it that bumps the 120vac house voltage to 230 volts. I'm 98% positive the transformer is bad and it was more than likely caused by a power company surge. I suggest calling for service since it is Monogram. It is more complex to work on. That said, I would ONLY trust GE Factory Service 1-800-432-2737 or schedule online at www.geappliances.com to have it fixed.

whats the model number?
