Ok in that case sounds like you are correct in your assumption it is the control board, This will need to be replaced.
To do this open the door, remove all the screws around the inner liner behind the control panel, Lift the control panel out, you will be greeted by the control board, At this point it will be a case of a couple of screws and swapping wires from old to new controls.Click here to order the replacement part
I recommend you purchase the part here since they give a full year warranty unlike other suppliers who only give a 90 day warranty.
