There is a thermostat I believe on the back panel of the oven. It is hard to tell exactly where it is by the picture, but it usually is in the back. If you click on your model # on this forum, go to the unit section of the breakdown of your oven. I believe you have to pull the oven out, and take the back panel off to get to it. Anyway, once you get to it. Make sure the power is off, when you do this, take the 2 wires off of it, and put the terminal ends together, and put some tape around it, so it does not hit metal, and then kick the breaker on, and see if the clock comes to life. If so, what happened is the oven got to hot in the clean cycle, and blew the thermostat. It diid what is was supposed to do. That thermostat is the so the oven does not burn down the house. The oven sensor is most likely the culprit. If you open the oven door, and look in the top back part of the oven, you will see a thin rod, held in place by 2 screws. That's the sensor. Unplug it from the rear, and take the 2 screws out, that hold it in place, and pull out from the front. The thermostat part # is 3149653, and the sensor part # is 8053344. If you jump out the thermostat, and clock does not come to life, you would most likely need the clock control. I would replace the thermostat also, since you are there. If you need the clock/control board the part # is 3169258. Tom
