Well, I wanted to update y'all.
I received my new control board and was able to get it installed today. Couldn't have been easier. Disconnect power, remove cover, disconnect plugs on the board, remove board, install new board in reverse order. Plugged it in, and hooray! The condenser fan kicks on as soon as the fridge fired up. Wonderful.
Too bad the entire board needed to be replaced...seems chinsy. But, I'm glad it was "only" a $90 fix.
Thanks again for the help, Jeff.
