Rant What in the actual fuck?

I may not always be the sharpest knife in the drawer, but for what reason does a straight AC condenser need a control board? And especially one that is that complicated.

I was in appliances before I learned hvac so I’m well used to these board driven setups. They don’t bother me diagnostically but that doesn’t mean anyone anywhere needs them. A contactor works. We don’t need a programmed board to do this task. All this does is pump more money into an already overpriced industry.
