Maytag dishwasher: need correct part # for control panel

Start button and normal wash button don’t work. Model MDB7609AWW1, Serial # FY3402910 White. I replaced the electronic control board and it worked once, now back to same status. I’m guessing I replaced the wrong part. Which control panel part number should I use 4434653 or 4434654?

I’m guessing that the only difference between those two parts is the color, white or black. So if you have the same problem, its the computer that’s bad.
