This time when I went in I found the immediate source of "no heat" was that one of the wires to the heat element had become disconnected.
I noticed the female terminal was fairly loose, burn marks on both female and male terminals, and also the insulation near the terminal had started bubbling. See pictures here:
My question is what caused this? The element and the high limit thermostat and the hight limt fuse all ohmed out good. Is it possible one of these high limit switches is faulty and does not trip when it overheats? Is there a way to test the component to see if it works? I think the fuse is a one-shot deal however - once it trips it is no longer any good.
Second question is a general configuration question. I reviewed a youtube video (thank you britishjames, very helpful!) to refresh my memory how to disassemble the dryer, and noticed that in the video, there is a metal shield positioned vertically in front of the heating element duct (A picture of it is included in my flickr set). On my dryer, this metal shield is horizontal (see the pics). Why are they different? Did I maybe somehow re-assemble this part incorrectly in the distant past? Are these shields positioned differently on different models, or is mine on wrong?
