300mm x 300mm 11.8" x 11.8" Microwave Oven Repairing Part Mica Plates Sheets (3 PCS)

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.

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! 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.

Good built quality

After tracing the old wave guide onto a mica sheet, I found the mica sheet cut nicely with ordinary scissors. The original, burned out waveguide had been installed with stainless pop rivets and silicone sealant. I wasn't able to get the pop rivet fragments out, so I ground them down flush with the surface. I cut the 100% silicone sealant tube point so I'd get a thin bead. I scraped all of the old silicone off there. IN ALL STEPS I MADE SURE I TOUCHED NOTHING THROUGH THE OPEN WAVEGUIDE PORT - SEVERE ELECTRIC SHOCK INJURY POSSIBLE. I ran a thin silicone bead all around the waveguide opening. I pressed the mica piece onto the opening. A day later, the new waveguide is installed securely and I am microwaving away!

Good value and quick delivery

I had no idea this product existed until my dad's microwave fell apart when I was cleaning it. I had to cut it to size but was easy to install and fixed the issue without having to replace the whole microwave.

Have to be careful when cutting to the size. I made a minor mistake while cutting which had me starting all over again but it was my mistake. The purpose i bought it for didnt work out for me but glad I was able to give it a try.
