Probably just lack of cleaning.Quite often this is due to grease or food particles stuck somewhere in the cavity of the oven or stuck on or behind the waveguide cover. It may also be in the area of the turntable support, coupler, or motor. The waveguide cover (also called a spatter shield) is usually about the size of a playing card and often held in place by a plastic rivet. It can be fragile, and the metal edges of the oven behind it can be sharp, so be careful! The cover and the metal behind it should be cleaned with a mild, non-ammonia cleaner. If there is any damage to the cavity, the area will first have to be sanded smooth and cleaned and dried thoroughly. If the cavity metal of the oven is cracked or split, you can use a small amount of steel-based epoxy such as JB-WELD to patch the crack or hole. Once that dries thoroughly, you can sand it very smooth. Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square. If your waveguide cover is burned, it will need to be replaced.It provides critical protection for the magnetron.You can order Dacor parts by part number from the Pros here.I would have been happy to link to the service manual if you had provided the model number.On the off chance that it's a DMT2420, the service manual is here and the parts list is here.

Always place the bag of popcorn on an upside-down paper plate.

This allows more microwaves to penetrate the bag from the bottom.

Also always place food of any kind in the microwave off-center on the tray, NOT in the middle of the tray.

Not only does it cook more evenly (think of how you stir liquid) but it also prevent the same spot from being heated repeatedly on the glass turntable, which can lead to overheating and breakage.
