Ice Dispenser will not stop

In the Door water dispenser lever broke. I purchased a replacement in installed it. During removal of old lever the ribbon cable came out of the control board. When I finsher the install and reinserted the cable the ice dispenser stated running and all the light came on. I checked the switch that is activated by the ice lever and it is good. It there a way to reset the control board? Or do you think it is the relay board. I probibly should have unpluged the unit before changing the lever, could that blow the board?
