OIIKI 5 PCS Waveguide Cover, Microwave Rplacement Parts Thick Heat Insulation Accessories, Universal Mica Sheet for Microwave Oven, for Frigidaire 5304464061 (4 Inch X 4.27 Inch)

While washing the inside of my microwave I cracked the reflective card. On a whim I tried Amazon for a replacment and wow. There it was. I got a pack of 5 or so for around $6.00. I broke the first one I tried to insert because I bent it. The card is not flexible. Next I removed the glass plate you put the food on, and slid the card under the plastic holders from the bottom towards the top, just under the holders. A perfect fit! You can turn the card around to adjust it to your microwave. Extremely happy to extend the life of my microwave.

I’m really happy with this cover. My relatively new microwave developed a scorched area in the waveguide cover which ultimately became a hole. My microwave started sparking whenever I tried to use it. I thought I was going to have to replace the microwave. I’m not handy at all, but I did some Google searching and found out the waveguide cover could be replaced. I went to Amazon not necessarily expecting to find such a random repair part available (and assuming if I did find the part that it would be expensive). I was pleasantly surprised to find exactly what I needed at a very low price. This was very easy to install and my microwave is working again without sparking. I feel like a superhero because I’ve never fixed an appliance before in my life.

These are great and I love that they come in multiple packs. I didn't realize these needed to be replaced as often as they should and I am thankful these are so easy to install!

In my microwave for a year now. Haven't needed to replace.

Microwave was making terrible noises. Changed the cover and it works great now. Almost bought a new microwave, glad I found these.

Shipped fast. I received on the second day after ordering. Dimensions fit my microwave oven well.

I was disappointed with the OIIKI Microweave Waveguide Cover for my microwave. The fit was not as universal as claimed, making installation difficult. After a few months, the material showed signs of burns, questioning its durability. Additionally, it didn't improve the microwave's efficiency as advertised. Overall, due to its poor fit, lack of durability, and failure to enhance performance, I cannot recommend this product.

Used for inside my microwave very easy to install
