Front panel was blank but when you pushed any button, the front panel all flashed. Replaced the control board. The board was easy to get to, it is in the back and when the 4 screws are taken off a plastic cover was exposed. The circuit board had 4 easy connect connectors. I ordered the board from AppliancePartsPros.com..They had the board in stock and I overnighted the circuit board. It was delivered on time..I had to be careful when installing the board because static electricity could destroy the board. Make sure you ground your body to prevent this. I easily installed the board. AppliancePartsPros technician sent me an email showing how to program the front panel. MAKE SURE THE FRONT PANEL FLASHES PE0000. Then I programmed from the instructions. If the board stays lit without flashing then, unplug refrigerator for 30 minutes. If you put in wrong code wait 30 minutes to reset the code...The technician was very knowledgable. I had called Whirlpool before contacting AppliancePartsPros and they were clueless. Also if you read the Internet on this problem it occurs 1 to 5 years after being purchased.
