Googled it & tried those remedies but, of course, the foil did not all come off. Ordered the replacement part. By the way, Appliance Parts Pros was the only company online that carried the exact replacement part. That I found anyway. The part was back-ordered, but I actually got it within two weeks. Replacement was pretty straight forward. Remove two screws. Taking out the old part was the hardest part of repair-lol-it lays flat, couldn’t get a hold of it, but after a minute we figured it out. Easy repair.
