Hi - we have a 22-year old GE double oven, model JKP27GJ. After a recent cleaning cycle, the door lock latch would not unlock. We gave it a day to rest, but still no luck. I removed the top panel and was able to flip the mechanical switch that was keeping the latch locked so we could open the door.
After the door was open and we started to wipe out the oven the broiler element basically disintegrated - broke into lots of pieces - totally burnt out. I replaced the broiler element and now the oven just won't get hot. On Bake or Broil - no heat. The lower oven won't heat up either.
