The heating element in this thirteen year old Jenn-Air double oven failed and arced to the frame the oven. The homeowner cut off the oven, but the arcing continued. He attempted to extinguish the arc with a fire extinguisher, but he was unsuccessful. The volunteer fire departed tried a larger fire extinguisher, but they too were unsuccessful. The arcing stopped when the electric meter was pulled. Unfortunately, when I arrived at the scene, the heating element was not present. However, arcing damaged to the porcelain enamel at the bottom of the oven was clearly visible.
