I tested the temperature sensor and it is reading according to the specification chart that came with the stove. But the control panel wouldn't go to 350 degrees. I replaced the control panel, which is easy to do. Now the panel will go to 350 but the temperature in the oven is at 735 degrees. That is not good. After going through the calibration of the controller temperature the oven works good now. It took 15-20 minutes to change the controller and 30 minutes to an hour to get the calibration correct.
