Thanks AJ. Problem was with evaporator motor drive on control board - fixed now. But the board has two empty relay positions (power to icemaker/dispensor and light cutoff relay). I wanted to make sure this is by factory design and that they didn't fall out -or something
I can see from the wiring diagram that those circuits are hard wired and not controlled by the main board - so the 2 relays are not required!
Thanks for helping me clear this up!
