    In a window unit air conditioner, for example; How does the psc work, when connected to the compressor run and start windings and the dual speed fan blower. If there is no centrifugal switch in either the fan or the compressor motor, how does the psc capacitor work, and is the start winding still in the circuit after starting, I know with a centrifugal switch the start winding would be disconnected after the motor is up to running speed. But it appears to me that with a psc wired is series with the start and or run windings that there is no way for the start windings to be disconnected.
