I have looked at the switch and really can't tell how to replace the switch. Anyone know how these go in and out?

All you have to do is unscrew it just like a bolt. There is a valve that is under it to prevent the freon from coming out. Just put a wrench on the nut looking bottom half of the switch and give it a turn. They are usually not too tight.

Heres a pic of what it should look like.

Thanks! I found my problem. It was actually wiring that had gotten damaged.
