Question about Microwave Ovens
When I pop popcorn, the microwave will shut down all power when done. It will come back on in about 20 - 30 minutes. I tried squeezing/tightening the fuse holder contacts and still had the same problem. It acts like something is overheating but only does it when popcorn is popped. Magic Chef MCO-153UW
We had the same problem with our brand new Magic Chef. Before going through the trouble of taking it back I called Home Depot. After talking to a Home Depot Rep I am told that the overheat sensor is under the glass plate directly beneath the popcorn bag. Popcorn gets very hot and the heat of the popcorn causes the sensor to shut the machine down. I would imagine this would be the same for a baked potato.
Very poor design.
I was told to put a microwave safe plate down and put the popcorn bag on it. This should help to reduce the heat and not trip the sensor.
A safety sensor is great, but not if it keeps tripping the machine and shutting down!

I have exactly the same problem with my Magic Chef. Microwave oven is brand new, it's actually the second one I've had in a week. First one did it the night I installed, OTR. I exchanged it yesterday and tried a back of popcorn as soon as I had the replacement installed. Same thing. Not using the popcorn setting by the way. Set the oven for 2:55 as that seems to be the magic number for getting all the corn popped. My theory is the steam generated by the popcorn is some how tripping a thermal cut off switch.

I am having the same problem with the microwave shutting down but mine shut down and it was not cooking anything at the time. It has completely cut off and I can't figure out why. I checking my breakers to make sure nothing had tripped and I even plugged it into a different wall socket and it still will not cut on. Can someone please tell me what to do to fix this problem? The microwave is not even a year ole yet and it was working ok before it shut down. Any help is appreciated on how to fix this.

I use mine and set it to reheat something and it shuts down. I don't understand what is going on. Can someone help me figure it out. This was in our 5th wheel when we purchased it. Don't get it! Why stop working in the middle of the cooking cycle. Then we push the start and it continues to cook. Go figure.

I'm having exactly the same problem with our Magic Chef, with Popcorn and with nuking potatoes. It does seem to be steam related.

If you read the owners manuaul, when heat from the rangetop below creates too much heat the fan will come on atomacitcally to reduce heat of internal parts of the microwave.. So I think when cooking a potato or bag of popcorn turn the exhaust fan on low to reduce heat builduldup,

That does indeed sound like the mag is overheating and the thermostat is tripping, but it's probably not the steam.
Do you feel a good amount of air flowing through the vents?
If the cooling fan is not running or the air vents are blocked, that wil allow the magnetron to overheat.
If air flow is not a problem, then you may have a defective magnetron.
Assuming it's still under warranty, it would be best to let a Magic Chef-authorized servicer handle it.
