Most likely the problem with your range is a bad key pad. It is not repairable and has to be replaced. Whirlpool sold it as a control panel assembly. It comes in two colors: white and black. The part number for the white control panel is
AP3030830 and the part number for the black control panel is
AP3030832
Here are the break down diagrams for Whirlpool range
Model RS696PXGB0
Good luck.
