Control board for the water/ice dispenser doesn't work

Hi, I have a GE Profile model# PSH25PGSA BV side by side and the lights/power to the thru-the door- dispenser doesn’t work. This happened two weeks ago, I unplugged the refrigerator, plugged it back in and it worked fine. Today, same problem, but would not come on when I reset the refrigerator. My question: is it the board behind the bottons on the dispensing panel? If so, do you repalce the whole panel or just the green board behind the buttons? Thanks Tom
