I have a whirlpool microwave, and I have no idea how this happened, but the piece of plastic like tape that goes over the holes on the inside of the microwave door has a huge hole in it. i'm moving out of my apartment soon, and being the nazi's that they are, they'll probably charge me to replace the entire microwave. The sealant/tape is about 18 inches wide by 8 inches high. Anyone know of a B&M store that I could buy it in? I tried Home Depot but they didn't carry it.
