I broke the wires on the ice maker and lost all power to the refrigerator, I replaced the main control board and the inverter board, I now have power and the unit runs, however, the control panel will not respond to settings, it displays 88 88, I've unplugged the unit and still no results, I did not replace the ice maker, just removed it, was told the unit will function without the ice maker, need help in figuring out what the problem is and how to fix it
