Product review (5 stars): Melted aluminum foil on bottom of oven fix!!
Ok, so I just moved into a house and the bottom of the oven had the paint scraped. I decided just in case, to line the bottom of the oven with aluminum foil. Yup, didn't know that new ovens have the heating element underneath, so it MELTED the aluminum foil. I scraped what I could off, but didn't feel safe cooking in the oven. I went on line & found the part needed. The hardest part of changing out the bottom panel was figuring out what to use. I've never used power tools, so I'm unfamiliar. After multiple attempts I found the right fit. I included pics of my screw, with square (not hexagon), I found the bit, and also the screw part. I took pictures of both, because I have no idea what they are called! 
After I got the piece out, I wedged a serving spoon under one side, then lifted & wiggled it out. Putting in the new piece was easy! I re-screwed the bolts in & viola! You can't even tell that I was the stupid person who melted tin foil on her new oven!
