Small 10 sec fire in microwave

Popcorn bag caught on fire. A microwave inlet cover on the top inside of the unit appears to be warped and has dropped down about 1/4 in on one side. Unit appears to work ok. Is my unit still safe to use?

Whirlpool had a recall on many microwaves due to this problem. Call Whirlpool and see if yours is one of them. My microwave model was mh7140xfb and was on the recall list.

Why did it catch on fire?


Any flaws in the painted surface on the inside of the unit will cause a spark and that generates heat. Examine the surfacecor any exposed metal. You have to use special paint to resurface the inside.

When I microwave small bag of Orville Redenbachers popcorn almost a third of the kernels do not pop and popcorn burns.


Be sure to place the bag with the proper side down on top of an upside-down paper plate, and put it off-center, not in the middle of the turntable.

Have a kitchenaid microwave KHMS2040WSS brand new. Is there a way to set the popcorn sensor for a smaller bag? Right now it is set for 3.5oz and burns all the popcorn.


I have never seen a microwave that doesn't burn popcorn if you use the "popcorn" button. Why the manufacturers keep putting them on I'll never understand. There's nothing you can do change the presets on an oven since they are built into the controller. Instead of relying on the oven, you should follw the directions on the bag. These tell you to use high power, stay by the oven and stop the cooking when the time between pops drops to 1 or 2 seconds. Stored heat will continue to pop kernels for a bit, and you won't cremate your popcorn. You'll also avoid the possibility of the bag catching fire and damaging the oven, which I have seen several times. Finally, don't expect 100% of the kernels to pop. There wil always be a few duds, and extending the cooking time just results in burned popcorn.

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 Dacor DCM24 microwave/convection oven is brand new and won't pop popcorn--old or new, large or small bag, with twice as much time as is on the bag, power on high. Doesn't work with the popcorn button...


Are you cooking it this way, as shown in the owner's manual?

"Use an overturned 9 or 10 inch oven proof glass pie plate on top of the
turntable when popping bagged microwave popcorn.
"

You can also use a paper plate in a pinch, but as always, never leave a microwave unattended while it's cooking, since some paper products can have impurities which will allow overheating and possibly fire.

This is a convection oven, so it has a metal turntable tray.

Microwaves cannot penetrate the metal from below like it would on a standard microwave's glass tray, allowing for even heating.

If you've lost your owner's manual, you can get it here.

OVERHEATING - Magic Chef Microwave M# MCO160S


Generic questions and comments:

Does your microwave have a "popcorn" setting and are you using it? Is there a rotating table in your machine? Is your popcorn bag elevated on top of a bowl or similar? Are you using some other "sensor" setting? Can you use straight time setting and get it to go past the 1 min 45 second mark?

On my microwave, it takes just about that much time and the popcorn is done ... BUT only if I elevate the bag to about the middle of the oven.

Let me know if this works for you.

I tried poping some popcorn in a brown paper bag and it caught on fire. I tried to the microwave again after i put the fire out and cleaned the mess up but nothing is working at all. No breakers were...


all microwaves have flame sensors that will cut the power in case of fire, this sensor will most likely have to be replaced. this will require you to drop the m/w and remove the case.

Fire from top of Microwave


It's not a dangerous or diffcult job for a do-it-yourselfer.

That would be the waveguide cover (also called the stirrer fan cover), and it would need to be replaced to prevent future damage to the magnetron.

Check your model number sticker to get the full model number with suffix and the manufacturer number (PACO1860AB0 for example).

Then you can find helpful exploded view diagrams and order parts by entering your full model number here: http://tinyurl.com/gv383

Good luck and good cooking!
