It is not that easy or possible to swap an ecm motor with a psc as the wiring from the circuit board has 16 pins for an ecm and a psc uses 2-3 and different relay setup. A psc still needs ductwork to suck against or it will not get up to speed either. has to do with the curve and design of the fan wheel.

not like the good ole days with a belt drive. :no: the young guys should carefully look at the spacing and curve and pitch of a wheel in a belt drive fan and then a direct drive to notice the difference. I have not seen a brand where you can swap an ecm with a psc but apparently york or goodman? has a terminal on the board for that?
