the oven shuts off completely when the bottom oven gets up to temp after about 15min. then the oven seems to reset itself after about 5min. but still will shut off after you try to put the oven back on. no fault code is given.
Actually it sounds like it is working correctly. It goes to the set temperature then shuts the heat off (otherwise the temperature would continue to climb), then when the temperature drops it comes back on to retain that setting. To test, time it with the door closed. Next set it. let it go to the temperature and shut off, then open the door to cool it faster. It should come back on faster.
