Review: Works very well like the original - Fit perfectly and worked like a charm great product and I have some for the future just in case something happens to this one!!!!🥰
Review: Saved our microwave! - Glad I found these. They are made of Mica and do flake a bit, but they did the trick and are the perfect size. Just slides in perfectly where the old one was- super easy. We only had our Sharp microwave under two years and I was ready to toss it. I already moved it to the garage to take to the trash and then started researching causes of sparks. These little panels being stained and burned seemed to be a major factor. For only a few dollars I decided it was worth rolling the dice instead of buying a new microwave. It’s kind of shameful the microwave manufacturers don’t really advertise that these panels when damaged cause sparks and can be replaced. This simple replacement panel saved us a ton since we didn’t need a new microwave after all. Thank you! Good deal, fast shipping. Plenty of spares for if/when one gets dirty and damaged make these a great value, I can definitely recommend.

### ⭐⭐⭐⭐⭐ Fixed our microwave oven!
*by R***O on February 26, 2023*

2 year old GE PEB7227ANDD started roaring and throwing out sparks. GE and most other warranties are only 1 year and a new built-in style oven was close to $700 with the $200 mounting kit. I followed Youtube diagnostics and found that the Magnetron, diode and capacitor were all still good so I fortunately didn’t buy a $150 Magnetron to see if it would fix it because it wouldn’t have. I then found a video that suggested the noise and arcing could come from a bad microwave antenna cover. These are in every microwave oven and could get worn out or contaminated with food splatter and should be replaced regularly. The official GE cover cost around $27 each but these generic ones cost much less and since the covers can be cut from a big sheet, I knew it was simple physics that the material wasn’t proprietary and that one brand will be as good as any. Sure enough, the fit was perfect and I didn’t need the nylon tabs to lock the cover in place, the slots in the oven hold it in place just fine. You can see the smaller sized cover in the $70 Hamilton Beach microwave oven we bought at Walmart to hold us over while we decided on a new built-in oven which we ended up not needing. Same type of material in the covers of all microwave ovens. Fast delivery, perfect dimensions, perfect fit and function. Someone else said you are supposed to replace these every six months (?!) but the manufacturers don’t tell you this. Regardless, if you have a stack of these stored away, it’s simple maintenance.
