Summary: I bought this microwave because it was inexpensive and I needed it to reheat food, and pop popcorn. After a little over a year it started to turn on by itself. The good news is that it started doing this while I was in the kitchen. Don't know what would have happened if no one would have been there. I'll leave that to the UL people who approved this thing. Avoid this thing - I'm throwing it away and spending more for a non-Magic Chef product.
Summary: This microwave was working fine for a whole year, but then it just turned off. And, I mean, nothing on it worked. The light inside went out, the display went blank. We had this problem with our first one, of the exact same model, so returned it to Home Depot, and they were great about exchanging it. It's been about a year, and we're starting to have the problem again. Magic Chef doesn't really care.
Summary: I bought the Magic Chef MCO160UB over the range microwave about a year ago. I've had intermittent problems with it going off while cooking for no reason. After it would set a few minutes it would power back up and work ok. Today it just came on by itself and I could not stop it by using any of the buttons on the control panel. I stopped it by opening the door. When I shut the door it would sit idle for about 30 seconds then start on its own again.
Summary: I purchased this microwave a little over a year ago based mostly on the low price as my home was on the market and my original microwave had died. It is the noisiest microwave I've ever heard but I've been living with it. A few days ago I put a cup of tea in to reheat it and pressed the One Minute button, and the whole panel went dark. The only troubleshooting help in the owner's manual was to check the fuse box, and the fuse was not tripped.
