I need a new ash pan gasket for my NPS40, but while it shows up on diagrams as #66, there is no part# listed for it, so not sure what to think. Is it same gasket material as for the door? Should I just buy another door gasket? Pls help. I have a slow burn despite great cleaning, and I do know a piece of this gasket is missing. How to get under there to replace it is another mystery....
