After self cleaning the upper oven, all heating elements do not work at all the different settings (bake, broil, roast). The convection fan will turn on. The selector and thermostat back-lights will turn on. I can hear a click when I turn the thermostat clockwise but the indicator light does not turn on.

The lower oven works. Which part should I replace and is there an instruction the comes with the part show me how to replace it?

Regards
