Even when empty. Searched online and found this as a common problem with burnt or worn out wave guide cover and it’s the number one cause. Luckily found exact size I was looking for and ordered immediately. What a bargain with 10pcs delivered next day, although only needed one piece. Easy replacement and microwave is back to life baby cooking hot meals without sparks. So happy, saved me buying a new microwave (had I not searched the issue online) Review: Fixed my microwave prefect - Great little product and a really cheap fix for my microwave! The mica waveguide covers fit perfectly and were easy to cut to size, making them ideal for a quick DIY repair. My old cover had burned through, and instead of replacing the whole microwave, this pack gave it a new lease of life. Who says white goods can’t be fixed anymore? These covers prove you can still repair things yourself without spending much. The only downside is that the pack comes with four covers when I only needed one — but on the bright side, it means I’ve got spares for the future. Overall, a simple, affordable, and effective solution for a common microwave issue. Definitely worth it! ## Features - 【Good Quality Material】Our microwave waveguide cover is made of quality mica paper with silicone resin by gluing temperature and pressed, high temperature insulation, you can use it for a long time - 【Wide Applications】This microwave oven repairing part is widely applied for home appliances such as electric hair-dryer, toaster, microwave oven, warmer etc.; Using them can extend the life of your microwave oven - 【Easy To Use】It's easy to trace and cut out; Simple replacement by using the old mica wave guide cover as a template while marking the replacement, and then simply using scissors to cut the new waveguide cover to fit - 【Nice Home Accessory】The microwave oven mica sheet protect the microwave oven from burning.It is a nice home accessory to help repair your home appliance, extend the life of your microwave, hair-dryer, toaster, warmer etc. - 【Package Includes】You will receive 4 pieces mica plates sheets in 13X13 cm/5.11X5.11 inch size, you could cut it into any size to fit your microwave oven, enough quantity can meet your daily needs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B081VJP32H | | Best Sellers Rank | 554,378 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 232 in Microwave Replacement Parts | | Brand | DesignerBox | | Customer Reviews | 4.5 4.5 out of 5 stars (362) | | Date First Available | 17 April 2019 | | Item Weight | 50 g | | Package Dimensions | 15.2 x 14.5 x 4.9 cm; 50 g | ## Images ![4 PCS Waveguide Covers, DesignerBox Universal Mica Wave Guide Cover Mica Plates Sheet Microwave Oven Repairing Part for All Microwave Oven or Other Home Appliances, Cut to Size, 13X13cm (Size 4) - Image 1](https://m.media-amazon.com/images/I/61MqyuDbv0L.jpg) ![4 PCS Waveguide Covers, DesignerBox Universal Mica Wave Guide Cover Mica Plates Sheet Microwave Oven Repairing Part for All Microwave Oven or Other Home Appliances, Cut to Size, 13X13cm (Size 4) - Image 2](https://m.media-amazon.com/images/I/618k5AotQeL.jpg) ![4 PCS Waveguide Covers, DesignerBox Universal Mica Wave Guide Cover Mica Plates Sheet Microwave Oven Repairing Part for All Microwave Oven or Other Home Appliances, Cut to Size, 13X13cm (Size 4) - Image 3](https://m.media-amazon.com/images/I/417MQM0g5gL.jpg) ![4 PCS Waveguide Covers, DesignerBox Universal Mica Wave Guide Cover Mica Plates Sheet Microwave Oven Repairing Part for All Microwave Oven or Other Home Appliances, Cut to Size, 13X13cm (Size 4) - Image 4](https://m.media-amazon.com/images/I/71sme4CJoDL.jpg) ![4 PCS Waveguide Covers, DesignerBox Universal Mica Wave Guide Cover Mica Plates Sheet Microwave Oven Repairing Part for All Microwave Oven or Other Home Appliances, Cut to Size, 13X13cm (Size 4) - Image 5](https://m.media-amazon.com/images/I/71XQc-Zo9mL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is it suitable for combination microwave stainless steel oven?** A: We have used them as replacements in our stainless steel oven **Q: does it come with glue** A: You don’t need glue, the sheet slots into place. In my microwave it is held in place by two small screws. **Q: Heat resistant** A: Yes **Q: It does say asbestos board. Is this true? This should not be allowed fore sale** A: The ones I received looked exactly the same as the wave guides that come with the microwaves I had to cut it to the same shape but it's the same material you find on ALL microwaves. I'm not a scientist so I couldn't tell you what it's made of but feels a bit like glass fibre ? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Replacement worked perfectly *by A***R on 10 December 2023* My microwave started giving sparks whenever I turn it on.
