Ordered new keypad and power circuit board from AppliancePartsPros.com Manuals and part numbers were available on the website. Found a video on line to help explain how to remove and replace the PCB.

I attached a piece of string to the old one when I pulled it out so I had a "fish tape" to pull the new one back through,
