Touch Panel buttons would not work

Removed the new panel from the box to see what needed to be hooked up electrically. Removed the old panel from the stove, disonnecting the electrical quick connects. Unscrewed the control board from the old panel, and then installed the control board on to the new panel. I then plugged in the two computer like harnesses. Reinstalled the panel, plugging in the electrical quick connects. The whole job took less than 20 min. to complete and everything works just fine.
