Electronic Control Panel doesn't work

Have a Kitchen Aid Gas Range Model KGRC608LSSO & the electronic touch control panel doesn’t work. Oven wont start pressing bake, will start pressing Bake (Convection) but temp. will be @ 300 degrees trying to enter a temperature on the number key pad will not work. When this first started sometimes a single number would not enter & had to rub you finger over the bottons and would work. Hope someone has a solution for me is the a comon problem with this stove???
