M931A2 PCB Rebuild Help

Good Morning/Afternoon/evening everyone!
I went ahead and got 2 more 5 tons to add to my beach fleet. (This may have become an addiction but thats not the topic today). I have a PCB box that i believe is the problem. It had water intrusion for sure. I pulled it apart and it has 2 solenoids and 1 circuit board. My question is mostly this, I see alot of boxes being rebuilt with no boards.
