Wow... I went to the Canadian site and I went to the parts link and the had the parts break down for free download but no wiring diagram.
I ended up finding the equivalent U.S. model # for my Cdn model (YKUDA230Y0F). The U.S. model # is KUDA230YWH0. I hope this helps to whoever reads this post.
There is 115VAC power present at the terminal connector for the pushbutton control switches. If someone could still give me assistance as to what could have happened, I would really appreciate it.
