Update.... Hopefully I won't have to resort adding the rooftop unit. I managed to get my basement a/c working. With the help of Airxcel, I installed a new control board (PC BOARD KIT 6535), and it is now all working correctly.
The new board was slightly different than the old board, but online directions from airxcel worked great.
Does the ac unit have to be pulled to replace the pc board
No. Mine did not. There is an access panel on the front left that comes off by removing 3 screws. Then you can see the PC board, the capacitors, etc.
Had to label each wire carefully because I ended up having to remove all the wires from the old board, mount the new board and re-connect up everything.
