Rob for Model Number JDS9865BDP We have a 15-year-old Jenn-Air duel fuel range model JDS9865BDP and when we set the oven to bake it reaches the set temperature but will not maintain it. If you cancel the oven and reset it, the temperature can be 25 to 30 degrees lower. If we use the oven on convect bake it seems to hold the temperature much better. I was told that the control board is likely the problem. I was told that if self-clean on the oven was used, the heat from the oven will damage the board on the bake mode but the convect will still work. I have replaced the temperature sensor and the door seal and nothing changed.
Answer Hello Rob, The control being damaged by the self-clean is from the heat produced by the self-clean cycle. You see, electronics have two number one enemies: Heat and moisture. During a self-clean cycle, the unit achieves temperatures of 900°F to 1100°F. This high temperature is what causes damage to the control board. This will not be limited to bake but can affect any circuit on the board. I would first check the resistance of the temperature probe 12001656. It should have a resistance of 1090 ohms at 77 degrees and would add 2 ohms for every 1 degree of temperature increase. If this tests good the issue is most likely a failed control WP8507P232-60.
