Dunno, but, how did you get on attaching the new door seal to
(presumably) the oven body? Mine droops at the top & I can't see
how it's supposed to be secured....

If this is a gas oven, then most/all have a gap in the seal at the top
edge,to allow exhaust air flow. Fresh air enters at the bottom rear by
the burner and exits at the top / front by the door.
