Question about Sunbeam SMW777 Microwave Oven
Like the heading states, the micro burst into flames earlier today. Flames inside the unit coming from the panel on the side. Not the food or containers. No metal or foil, just flames from the inside of the unit into the the interior. Only 8 months old, manufactured in May 2005
That panel is called the waveguide cover. Its purpose is to protect the wavegudie and the magnetron from grease and food particles. When grease and/or food particles build up, they arc and spark. If it is not too damaged, it can be removed, cleaned, and reinstalled. You should also clean just inside the opening (waveguide) with a damp cloth, but be careful of the sharp edges. If it is too damaged, it will need to be replaced or the magnetron will eventually be damaged. If you can't get parts for this brand you can cut a new one out of waveguide material. I would take the old cover to an appliance parts store in your area. Once it is done, be sure to keep the cover clean. A sample photo of a waveguide cover is attached.
