Oven said "fault detected", had repair person change oven sensor, fault detected again. Oven was way too hot (runaway temp). Told to change control board and I did. Now with a new sensor and new board, I still have an oven that overheats and when I set it to 400f it jumps to 500+ and I have to turn off the oven. Any advice? Much appreciated!:eek:
I used a digital thermometer hanging in the middle of the oven, not touching anything, to check the temperature as it heated. The board was not telling me the correct temp. When I shut it off and set it for a new temp it showed me a different oven temp than it did before.

Thank you so much for the reply. Alas, I don't have a multimeter and I know the repairman did check the resistance and it was fine but I don't know if it was just the sensor or the wiring as well.
