My double oven gave me an F1 error code, and I tested the bake elements, broil elements, and temp sensors. They all test ok. I pulled the oven out and noticed the top temp sensor's connection was loose, the little plastic thing that holds both connectors was broken, and the female connection portion was brown as if burned. I decided to change both temp sensors. I also decided to change the wire harness, but could not find it, so I ordered another harness, for another model, that had the same type of connector for my temp sensor. When the new harness arrived, I cut both new and old wires going to the top sensor, did a little wire surgery, and reconnected this "new" connector to the top sensor. I turned the oven, and viola, both ovens worked like a charm. My wife started baking, and mid-way into it, the oven started beeping and gave an F1 error code again. HELP!
