This could be a couple things. We need to start with checking the voltage coming out of the control module.

I attached the wiring diagram below. Can you back probe each wire and operate that system and tell us what the voltage is coming out of it?
Also, after you replaced the control board, what this the entire assembly or just the circuit board of the unit? Can you get a picture of the part that you removed just so I can get on the same page as you for what you replaced?
Thanks
