The White Knight is a run capacitor system i.e. the start and run
windings are both energized when the motor is running. A capacitor start
motor is usually much bigger and has a means of disconnecting the start
winding and capacitor once the motor is running, either by the starter or
a centrifugal switch.



Ah, that's a PSC (permanent split capacitor) motor. Low starting torque
but simple, cheap, and generally reliable.


using an electrolytic capacitor



If it uses an electrolytic capacitor that would explain why the
capacitor fails. Most of the dryers I've dealt with have oil filled run
capacitors, as does my drill press and the fan motors in my furnace and
heat pump, those are are all the PSC motors I have I can think of other
than the refrigerator compressor, dunno what sort of cap is in that,
I've never looked.
