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.
Your power level should be on high, but you shouldn't rely on the oven to time the cooking. I have yet to find an oven that won't burn popcorn if it has a preset POPCORN button. Press it and walk away and next thing you know, you've got charcoal. You should always stick around while making popcorn. Stop the oven and take the bag out when the time between pops drops to 1 or 2 seconds. The corn will continue to pop on its own for a bit because of stored heat, but you won't burn it. You'll never get 100% of the corn to pop, so don't worry about unpopped kernels.
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.
Because the microwave energy is beamed into the interior of the microwave and then dispersed by a metallic "stirrer," the pattern of the energy can be fairly consistent, rather than completely random. But this pattern sometimes causes certain portions of the food to overcook (creating tough spots) and others to undercook. A microwave oven with a carousel is far better at cooking the food consistently--the pattern becomes quite random while the carousel is turning.
