Those door gaskets were getting hard to find more than a decade ago.

About 6-7 years ago, I sent an NOS 302448 gasket off to be analyzed for reproduction. Once received, they said it could be repopped for $120 each using modern silicone rubber which is probably superior to the material originally used. I figured that price was more than most would be willing to shell out. Besides that, there's very little demand for these gaskets, which is probably why Maytag discontinued them in the early 2000's.

I posted this drawing of the dryer door gasket profile back in 2014 with the hope that someone would find something similar available and share it with the rest of us. The portion that hangs down on the far right butts up against the closed door and forms a seal. The part hanging down just to the left of that tucks into the gap between the dryers front panel and the drum cover forming a seal there, and the rest just extends into the drum. This drawing is based on a well used original that was worn out but still had a few good areas, so the dimensions might vary slightly from a good new one.
