Waveguide Covers for Microwave, Juerly 4 Pack Mica Plates Sheets Heat Insulation Board for Universal Microwave Oven Repairing Part - Cut to Size, 5.1x 5.1inch

I can't believe these are a thing for microwaves. Never seen one with a 'mica' shield until we had to book a stay at an airbnb for about 5 months. The house has this little microwave that had a mica shield. It had seen better days and eventually fell off and broke. I used a piece of wax paper to mark the notches on the microwave that held the sheet in place and I just transferred the pattern on the mica sheet and cut it out and notched it where indicated and just slid the new one in place. It was cheap enough that I didn't mind eating the cost of the sheet and the owner now has extra mica sheets.

Es la segunda vez que los compro porque se les quema seguido a los hornos y son de muy buena calidad. Me gusto que los pude conseguir a muy buen precio

Was unsure if I should've bought but it was worth it. Fixed the problem. Easy to cut.

Worked fine, easy to cut, and came on time with no damage. Exactly what I needed.

My microwave was sparking so I bought these, hoping to fix the issue. However, later it turned out the sparking was caused by empty microwave (as long as I put food in there it is fine). Anyway, we still used these new covers, however, they are much thinner than my original one. I hope they were twice as thicker, just like the old one.
