Temp sensor resistance should be 1091 at 75 degrees. Measured resistance was .772. I ordered a new one and the resistance was .774, so I guess the old one was fine. I replaced it anyway and I still get the same condition. If I try to preheat the oven with the broiler to 350 it gets to 150. What can I investigate next?

Do the bake and broil elements work? I am not sure why the oven sensors are reading so low. Could be something wrong with the meter. Also looks like you ar using too high of a meter scale. Since the expected resistance is about 1,000 ohms you should use the 2K scale.

I used two different meters so the meters are fine. Yes, both the bake and broil elements work. How do I determine if the control board is bad? Is there a way to perform a reset on the board?

So the norm is if the oven sensor is OK then the board is the likely culprit.
