My broil shorted out. we took it out. we did not replace it as the oven element still worked. I cleaned the oven last week. when I went to use the oven again it worked for about 10 minutes, then tripped the breaker. we took the baking unit, sensor fuse, temp probe, to the dealer and they all work. so what is next? the board. the stove top and the lights work but the preheat time does not work I am guessing because the element is not in it.
