Christina K Buchanan , GA March 29, 2015 Smart board fried Took off top grill vent, unscrewed one screw on top of display keypad panel, pulled keypad panel out ,unplugged 4 or five electrical board plugs, unscrewed 4 or 5 little screws removing the circuit (smart board)panel from key pad panel. Found correct picture and ordered part. I am a housewife so if I can do it you can do it. Part was expensive but worth keeping the microwave to me. Works great.
