My neighbor just did this last week. He bought a whole new heating coil assembly for his Whirlpool before I walked over with my meter. The fuse was blown, probably from a clogged vent. What's the most expensive part replacement you've seen someone do before they found out it was just that little fuse?

Yeah, that breathing thing is real. I mean, those little pin tacks can pull everything out of square if you're not careful, exactly like you saw. Joel280 is right about the little things too, it's all about the flow. My version of that was an old pipe welder telling me to listen to the sizzle, not just watch the puddle. If it sounds like bacon frying right, your heat and speed are good. Changed how I set my machine for good.
