Kenmore E0 F2 error code

I have been searching the forum for this error code and have found that it is either the keypad or control panel. I have tried unplugging the range and then unplugging the ribbon to the keypad as suggested in one of the forums. I have plugged the range in to observe for an hour as the forum suggested and got a new error code of E1 F2. I have tried searching for parts for my model number but there is not a match for my model. Please advise.
