You may need to change the I/O board usually around 420 to replace. once you take the top and right cover off look at the I/O board the connector at the bottom is for the keypad sometimes this comes loose and can cause the keypad to not work correctly.
enter test mode
when the oven is off press back and enter at the same time then type in pin 9428 then press enter
select self test and follow on screen directions
hopefully this will give you some insight as to what is wrong
if you have any problems entering test mode and you have checked the connector and the bottom of the I/O board just replace the I/O board
