Ceasar asked 4 years ago
I need to replace the wave guide cover in my microwave. I bought a generic piece of mica and using the old one as a template. The old waveguide cover was held in place by 2 screws (metal I think) which I misplaced. Can I attach the new cover with any type of screw or were the original screws a “special” microwave safe metal screw?
