What most likely happened is when you put the oven in the clean cycle, it blew the thermostat in the back. What you can do is take the oven out of the wall, and take the top back panel off, and in the middle there will be a round part, with 2 wires coming to it. That is the thermostat. If you have a meter ohm it, out. Make sure you do this with the oven power off. You could jump it out if you like, and turn the power on, and see if the board lights up. If so, you need to replace the thermostat, and the sensor, because ther oven got to hot, and blew the thermostat. Oh, don't run the oven with the thermostat, jumped out. It is a saftey, and it did the job, so oven doesn't burn down the house. PROMICE?????
