todmngd,
If the "F10" appears while the range is in "time of the day" mode then the problem is a bad EOC.
If it appears in the "cook" mode then the oven temperature sensor has to be checked first. It could be a bad wire harness and/or sensor plug.
- The part number for the EOC is
AP3790798
- The part number for the oven sensor is
AP3363354
