Our microwave works like new!! ### ⭐⭐⭐⭐⭐ pretty good! wondering why you need a 6 pack. *by R***P on January 29, 2026* works. its a wave guide, hard to mess up. ### ⭐⭐⭐⭐⭐ 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/428228285-bojack-microwave-waveguide-cover-universal-cutable-mica-board-for-microwave](https://www.desertcart.tn/products/428228285-bojack-microwave-waveguide-cover-universal-cutable-mica-board-for-microwave) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
