I removed the oven door by unlocking the hinges and pulling out. Set on workbench (with towel/pad) and removed handle, four screws, then bottom and inside panel screws, then one nut to finally be able to get at the inner glass insert. Removed insulation and then took an extra hour to really clean all surfaces (middle glass was quite greasy due to inner glass being broken for a while. Reassembly wasn't bad, but took a while to figure out that the two thin 2" red spacers belonged around the two handle screws. This was tough to figure out as they come off when taking the handle off, but you can't see them, so didn't know where they came from! Anyway, if you're just a bit handy, you can do this job.
I pulled the oven door off the hinges and took the bolts out of the bottom of the over that were holding the strip on. I then pulled the strip off and replaced it with the new on. I replaced the bolts and then replaced the door on the hinges.
We ordered the part from Part Select, got it within a week and replaced the door. It is a little tricky because one has to dismantle the entire door to do the repair (inside screw to undo). You'd preferably be 2 to do the repair, although one can manage.
