I don't want to pay $100 + for the pressure switch if it is really the control board. Thanks in advance.

You need to check the switch with a meter. It's very easy to check: Just remove hose from drum and blow on hose while checking with an ohm meter. There no reason to buy parts you do not need if you check them first.
