I figured out why my MB stop heating last weekend. I torn out the element and found that it had shorted out. It looks like they had some kind of plastic backer between the back wall and the contacts for the element. Well a short occurred on the right post with the back wall. You can see in the picture the plastic backer and the right post. The problem with the replacement of this is the right wire has gone up inside the wall cavity. And everything is riveted together so fishing it out is going to be a pain. I will try calling MB tomorrow to see if I can get a replacement unit. If not, my quest for a gasser will continue.
