ice dispenser and water dispenser not working

our cover fell off for the ice and water dispenser and in one of my weaker moments i plugged the wiring harness in upside down. it no longer gets power to the door panel where the controls are. it was working until i did this and has not worked since go figure. totally my fault! just trying to find out which part to replace. i do know the main control board gets power. got a shock when i accidently touched back of board. i do believe the wiring harness still works i tested the harness and all connections with meter. any ideas on what part could be bad my Guess is bad control board but i am also the guy who broke it and got shocked. i would appreciate any help
