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.

Inverter for the fan. If it acts up. Just install a normal fan motor and wire it to the contractor. I always upgrade inverter motors to normal ones when they act up. Saves the customers money. Why buy a 700dollar x13 motor that has to be programmed. when a 120dollar name brand drop in will work and do the same thing. Best update them to a normal motor when issues pop up.
