Took the dryer down for a lack of full heat,, noticed the cabinet and flue piping was full of lint, took all the parts off and cleaned everything, I believe it was "leaking" heat around these gaskets. Easy to install the gaskets and I have the dryer back together. Jury is still out on total drying now till the wife uses the dryer, but I think it'll be OK.
Best part of the whole deal was the shipping time, got the parts very fast.
