In reading other user's posts, I inferred that it was a possible board problem, not the control panel. I took a chance and ordered the board and it only took a couple of days to get it! It only required to take out six screws for access, then three screws to take out the board. It was a simple job to replace it. I'm a techie, so it was like replacing a motherboard on a PC.
It took about 15 - 20 minutes to do, most of the time was spent trying to get the panel back on properly.
In the past, I've used Appliance Pros to get the replacement part for the ice maker on my refrigerator. That came within three days! The videos are a plus, too.
I will definitely use them again!
