I had one of my hvac units in my property fry 3 boards in succesion until we found the culprit.Condensate was getting blown around near the controls and apparently reached the board.By the time my hvac guy showd up to diagnose the problem,there wasn't any water present.Finally figured it out the last time as we inspected the unit right after it failed and saw the water.The culprit?The condensate line was slighty plugged and the pan wouldn't drain as fast as usual.After and hour the pan would be dry and this wasn't something that would be obvious to look at.Blow those condensate lines out.
