I was using my oven a few minutes ago and when I heard a large buzz and glanced over and saw a bright flame in the oven. I turned it off and discovered that the heating (baking) coil was on fire and burnt through. I called GE and they have the part. Has anyone replaced a coil in an oven? It looks like there are two screws on either side that might looses and tighten the part. Any info will be helpful. The part is $74 with shipping. I figure this is cheaper than an appliance repair guy.
