Kenmore built-in oven set at bake tempature does not set just keeps rising got F2 code

HI. This error code will occur when the control board senses an oven temperature above 915F-935F

Once this type of temperatures occur, this will generally weld the relay contacts on the main board. This will damage the board, and it will require you to have it replaced, asap. If these temperatures never reached the sated thresholds, i would advise to Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace the sensor if found to be defective. Check door lock switches for damage, as well.

In most cases, this will be a failed control board. To confirm, simply preform a resistance test on the sensor. The normal ohm readings should be 1100 ohms at room temperature.

If the oven temp sensor dose not test out at 1100 ohms at room temp, replace the sensor.
