I have purchased a new control board for my wall mounted oven. After removing the damaged control board and then installing the new board, only the clock will light up and not the other display. The buttons all make beeping sounds when pressed, but nothing else seems to happen. Does a new control board need to be programmed with oven cavity size information before the new control board will function? Do new control boards have a default oven cavity size already programmed into them? Help please?
