My oven started arching with micowave popcorn (4 or 5 different times). Now it will not heat. No error messages on the screen and everything else works. Thanks Dennis M.

Your magnetron is overheating and needs to be replaced.

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...

Call the serviceman

in 99 % of cases the problem is the magnatron it is a very expensive part and unless the microwave is well worth the money we normally write the units off


sorry (

but i hope this helps

Hi,
Here is a tip that will help you to figure out what is wrong with yourMicrowave Oven....

Basic Microwave Oven TroubleshootingTips

If the microwave functions normally while cooking everything else, but is only burning popcorn, there is no component problem that will cause this. You cannot adjust or replace any internal component to make it not burn popcorn. All power levels and program options are contolled by the consumer at the control panel. Refer to your owner;s manual for their recommendations.

If the oven is equipped with a popcorn feature button, it is programmed for a recommended power level and time. This is an ESTIMATED program feature. The manufacturers of both the oven and the popcorn will also give directions that tell you to turn the oven off when the popping slows to about a pop every 2 seconds. Failure to do so can result in burning.

If the microwave does not come with a popcorn feature button, the manufacturers of the popcorn have directions on the outside of the box that tell you what POWER LEVEL and TIME to set the oven on for the desired result. Again, the you still have to listen as the bag pops to ensure it does not burn.

In addition, on some microwave ovens, there is a feature that allows you to select the SIZE of the popcorn bag. Some popcorn manufacturers have smaller snack size bags that don't take as long to pop. You have to select the appropriate size to get the correct program option.

In any case, you never are to place popcorn in a microwave oven and walk away from it. All these program features are ESTIMATIONS based on manufacturers testing and recommendations for the best results. All microwave ovens are different and operate at different power levels. Your best judge is to listen as it pops.

I hope this helps you.

Replace. Sounds as if the magnitron has gone out.

Good Luck

Sadly popcorn kills more microwave ovens than peiple imagine. You can get an estimate on a repair but I believe you will probably decide in the end to replace it. Same exact thing happened to me............expensive popcorn!!

Sounds like you have metal inside oven, and arching can happen if nothing is in there to absorb energy.

use a mild cleanser like soft scrub with bleach!
