This couldn't have been simpler! Removed the glass panel by taking out 4 screws on the bottom that were accessed by opening the oven door. Lifted up, then pulled the panel forward, released one electrical connection, and the panel was disconnected and could be laid on a flat surface. Unscrewed the four nut screws on the old control board with a socket set (you could use a small wrench, but it would be tedious), un-clipped the wide ribbon connection ( had to pry it off very gently to avoid damage) and that was it! Simply reverse the process to install the new board. I'm thrilled- the display has been out for a couple of years- what a pleasure to have it back!
