4 Pieces Waveguide Cover Mica Plates Sheets Microwave Oven Repairing Part 13 x 13 cm with Scissor for Use Universal Microwave Oven

The cards work fine, at least the one that I needed. The scissors aren't really made for cutting rounded or sharp corners on thick cardstock: it causes metal flakes to come off the card, but doesn't seem to affect performance. Should prefer a hobby knife or box cutter, make multiple passes. If you plan to keep the same microwave, you should trace out the original shape on all the plates before tossing so you're not making copies of a copy later. Really easy and economical replacement compared to buying a whole new machine.

I initially found a pre-cut mica sheet on Amazon that matched my microwave perfectly, but it was too expensive and had a long delivery time. So, I decided to try this customizable mica sheet set instead.At first, I was worried about cutting out the small holes, especially after reading reviews mentioning that the mica sheets can break easily. My first attempt didn’t go well—I accidentally damaged a piece. On my second try, I used a sharper pair of scissors, but it still required a lot of force and precision to cut out the shape. To make the process easier, I used a utility knife, carefully pressing down multiple times to carve out the small holes.In the end, I successfully cut the piece to fit my microwave, and now it works perfectly again! I’m so proud of myself! My microwave model seems to have one of the most complex mica sheet shapes, so I believe cutting for other models should be even easier. Highly recommend this product!

Worked like a charm! No need to buy a new convection microwave 😃

Material is fine, scissors useless. Easily cut with precision with an xacto knife.

Used as a replacement in my Samsung Microwave. Just outlined the old one on to a sheet.It comes with a scissor but I would use a utility knife or razor blade to cut it.It is brittle, shreds and tears easy.The final product worked perfectly

I bought this to fix an LG microwave oven that started arcing. The first thing to check if that is what you have going on with your oven is the microwave guide plate on the side of the oven. If it is burned or discolored the guide plate needs to be replaced. If you can find the correct one for your make and model, order it. That was not the case for my LG. This "kit" comes with four pieces. You have extras in case you miscut one or two or even three. As per reviews, I did not attempt to use the included scissors...they are garbage! I used a nice old-school sharp shears that I have, as well as a snap-blade razor knife with a brand new blade. DO NOT attempt to use the scissors that come with the kit or a dull razor knife. You would be setting yourself up to fail! I used a thin mechanical lead pencil to trace the outline. The above all being said, it is a very easy task to cut out the new one using the old one as a template. Once trimmed up and installed, my microwave worked like new again. Be sure to clean the inside of your oven completely before installing the new waveguide plate. Especially, clean around the opening where the plate was removed. Wipe everything down after cleaning, with plain water to remove any soapy residue. A few last tips. If you are melting butter or heating oils of any kind, be sure to cover the container that they are in with a paper towel. It is the grease on the waveguide that causes it to arc and malfunction! Also, UNPLUG the oven before doing anything inside of it...there are dangerous voltages in a microwave...4000 or more to be exact!Finally, NEVER run your microwave empty! Put a cup of water in to test it!

Remove defective part and used it to trace over sheet. Need to use scissors ( included) but also a straight edged razor blade or utility blade. Need to bend new piece slightly to fit in tabs. Microwave works great now!
