I unplugged the oven and then removed the back panel. Next I started started removing cables from the old control board one by one, being careful to plug them into the same place on the new board. There were some slight differences in where some cables were located, but the ports are labeled and you can just match it that way. Then I applied the new faceplate to the new control board. I unscrewed the old board and screwed in the new board. Very easy replacement.
