Saturday, in the middle of baking cookies, the bottom element started sparking. We turned off the oven and it kept going. I dumped all the baking soda on it and, when it kept going, a cup of flour. That didn't slow it down, so we tried the fire extinguisher. As we pulled it out from the wall to unplug it, the flour blew and the element broke in 3 pieces. I had an experienced friend replace the element. There was a hole in the back wall where the element used to connect. He took the back off, cut back and stripped wires, attached a new connector and replaced the element. Now, I have nothing - no clock, no burners, no oven. Yes, I reset the breaker and checked that the plug is snug (that's the extent of my knowledge!). He's going to come back tomorrow with a meter but is it possible I totally fried my oven by exploding the flour?

The new lugs were longer and shorted out to the back panel. They are wrapped in electrical tape now. Should I get some kind of heat tape? If so, what?
