Help with pc board on basement a/c on 96 Winnebago vectra

I realize this does not answer your question and probably not want to you hear...A friend with basement air once the extended warranty ran out gave up on it and put two roof units on. During the three year extended warranty it paid over $2000 fixing it and when it broke again on his dime he gave up on fixing. Made it into a basement storage area when he threw it away.
