Hi, thanks for using JustAnswer.com. I suspect your motor control board is shorted and is causing the issue you are having. I believe you are replacing the main control at the top RH corner, correct? Remove the rear cover and look closely at the motor control board mounted to the bottom of the cabinet. You will likely see some visible burn marks on that board. Let me know what you find and what part number control you are replacing.
Part number for the harness is W10204534, available from http://www.appliancezone.com/ for $16.60 + shipping. It is number 1 in the picture...
Wow, that's awesome! I am still a die hard Whirlpool fan. If it were me, I'd go Whirlpool. Stay away from imports like LG, Samsung, Bosch, Asko. Whirlpool and Frigidaire are pretty hard to beat. Ya gotta love Costco!
