Used the diagnosis on your website to determine most likely problem was oven temperature sensor so I ordered the part. Really surprised at how fast it arrived even with ordinary shipping.
Watched your "how to video" several times and followed steps. Did encounter two issues. First, easily resolved difficulty was removing connector on existing sensor due to pack-up of insulation that prevented its removal through oven wall hole. Small long-shaft screwdriver used to move insulation to each side to solve that problem.
Followed advice to remove door...easy and clearly necessary for easy access to sensor. Putting the door back in place however turned out to be a major task. Video and range owner's manual proved not very helpful. Perhaps there is a need for another "close up" video on how to get the door back in place. I could see what had to be done but had a difficult time in getting the door to cooperate!
