Touchpad on GE Trivection oven not responding

several keys on my GE Profile trivection wall oven not responding; model number JT980SK1SS. Do I need to replace the board, glass touch signal board or the front panel? I think we need to replace one of the following but I am not sure which. Buttons on the left and right are not working so I think we need to replace the main board. Suggestions/assistance appreciated.
