On this GE gas stove, the oven does not work. If you put the selector switch to bake or broil and turn the thermostat on, the indicator light does not come on and the ignitor does not light up. But if you put the selector switch to self clean and turn the thermostat all the way to self clean the indicator light comes on and the ignitor lights up and lights the bake burner flame, so the self clean works. I suspect the thermostat or the selector switch, but not sure which one. There is no diagram.
