Review: Worked like a charm - My existing mica plate got damaged from "cleaning" and it eventually just fell off the top of the microwave. I cut these to size and put them on and it's been working great. I'm more careful with the cleaning so i don't get them wet and i think that will keep them from damage.
Review: Fixed my own microwave! - My microwave started sparking one day and cleaning didn't help. I figured out I needed a new waveform cover, but guess what? The part is no longer available. Ordered this and made my own. Top photo is the original burnt out cover; bottom photo is the one I made to replace it. Popped it in and no more problems. Much cheaper than a new microwave! And this was about the ONLY product I could find that was large enough.

### ⭐⭐⭐⭐⭐ Worked great!
*by G***S on October 15, 2025*

Worked great! The sheet was easy to trace on, cut out, poke the screw holes, and install. This mica seems to be thinner than a recommendation for long term use, which I found on a howto site, but I now have a safe microwave with extended life and plenty extra mica if this cutout version does not last as long.
