Is not normal for a microwave to shutdown after 4 minutes of operation.
From the info you are providing, It looks like the magnetron might be overheating causing the thermal fuse to shut it down until it cools down. There may also be a loose connection in one of the switches or a cold solder joint in the low voltage power supply.
I would suggest to check and make sure that the fans are functional, If always did; it could be that there isn't much air circulation where the appliance was installed.

Shut's off after cooking popcorn, only popcorn, won't restart for 15 too30min.


Sounds like the magnetron is over heating. Try putting a 4 0z cup of water in the oven along side the popcorn bag. See if this helps. Usually, the oven only runs 2 to 2.5 minutes for a bag of popcorn. You may have to experiment with the slightly different cooking time...

MCD1611W New, popping popcorn in glass MW corn popper. 3-4 minutes to pop. After popped I open the door and after a few seconds the MW shuts down completely, no lights, no response to pad pushing.


Popcorn is a low-moisture food which can cause a microwave to overheat, as can a failure of the cooling fan or blocked vents.

You should always turn a paper plate upside-down on the turntable (slightly off-center for better heating) and place the popcorn container on top of that.

The paper plate elevates the popcorn for better exposure to the energy and protects the turntable from excessive heat.

Placing food off-center instead of in the center increases exposure to the energy and prevents the same spot on the turntable from being overheated repeatedly, which leads to material fatigue and cracking.

It's also a good idea to put about 1/2 cup of water in a 1-cup microwave-safe container in the corner of the oven when cooking low-moisture foods like popcorn, bacon, and potatoes.

The microwave's magnetron has a thermal protector (thermostat, TCO, or thermal fuse) attached to it.

If the magnetron gets too hot, it can be damaged or destroyed, so the thermal protector opens and disconnects the power to the whole oven.

If it is a resettable device, the power will be restored when the device cools. If it is not resettable, the device must be replaced.

Over heating and shuting off


I am not surprised! Cloth of anysort is not recommended to be placed in a microwave oven!

That includes undies and socks which many try to speed the drying time of.

Regarding the popcorn.. The oven is overheating due to a possible containment in a hutch, where insufficient airflow is available to lower the temperature. Pull the unit away from the wall to allow more airflow, clean the vents and help it breathe.

My Magic Chef over the range microwave won't even pop popcorn without shutting down. Was told to put dish on sensor but it still shuts down. Any answers?


Magic Chef customer support recommends placing a glass of water inside the oven to absorb some of the energy. It works for us..Jan 1, 2010

Shuts down for 5 minutes


I have the same problem with my new magic cheff over the stove microwave oven. I call magic chef and they gave me the 800 number for the service center (1-800-775-0202). When I described the problem they told me to just put a plate under the popper and this wouldn't happen anymore. I haven't tried it yet but here's hoping.

Oven turns off


Hi,

You are running the risk of damaging the Magnatron by doing this.

Check the packets you are using, you will have to reduce your power output.

This is because microwaves act by being absorbed by water. There is very little in popcorn and in fat. Once this has been evaporated, the microwave energy builds up (as it is still being produced - but not absorbed), and ends up cooking the magnatron itself.

I have seen countless posts on here after cooking popcorn!

More fun on the hob anyway - and cheaper to buy in bulk!

The cooling fan is a must!

Otherwise, the magnetron will be ruined, and that drives up the repair cost.

Magic chef microwave shuts down


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!
