The motor for my pool filter pump motor (plate picture attached) has recently become slow to start. I swapped the capacitor from a different pump (condition unknown) without any change in results. It is a single 50uF capacitor and I'm not sure if it is for starting or running the motor. Once the motor picks up speed in less than 5 seconds, it runs fine.
Show I purchase a new capacitor or look for the problem someplace else?
