As I was cooking popcorn last night I noticed a plastic burning

Customer Question

as I was cooking popcorn last night I noticed a plastic burning smell and noticed that there was a burning glow coming from the inside top of the micro wave...I shut down the oven immediately. the stir fan cover had a black spot on it. I touched it and the plastic was melted and there was a hole in this cover. What caused this... I quickly unplugged the microwave and had nightmares that my house was going to catch fire

So that cover that was melted is called the "wave guide". Usually this occurs from food splattering on it and then the microwaves reacting to one small spot causing it to melt. Just replace the cover and run a cycle and make sure it's all better again. If not, then you would need to replace the microwave because the microwaves from the magnetron are arcing out to things they shouldn't. Below is a link to the cover you'd want to order and replace.
