If the buttons deflect when pressing them, it is probably a diaphragm key matrix, but you would have likely found that with your meter. http://pcbheaven.com/wikipages/How_Key_Matrices_Works/
If there is a solid surface with no button deflection, then it is probably a multi-electrode capacitive touch sensor with an integrated controller and some simple bus connecting back to the "computer". https://www.sparkfun.com/products/9695 I assume this control panel is for the oven/clock and not the range. A residential gas burner without a mechanical knob/valve is pretty rare. -- Kenny -+---+++-++-++++--+------+-+-++--++--+-+-++--+++-++----+-++-+++---+----+--+----+
