So I went to replace the board because well it's busted lol, but after replacing the board I had found the wire for l2 was switched with the fan wire that goes to the fan capacitor. This control board was replaced less then a year ago, and there is a jumper on r to g , this is an electric furnace in a basement laundry room for a big condo building. With the the new board I could get the molex plug to connect to the board and that's when I really looked at the plug and saw it was busted. Would have those wire mixed cause this to happen?
