If not on properly, the pump will suck in air and the pump will not be able to prime. Our in-ground pool pump (Hayward Super 2) would not start this morning - the switch turned on, it hummed for several seconds, and then shut off. The unit of capacitance is microfarad. A start capacitor will normally fail open, and this can be tested with an ohmmeter or a capacitor tester. After installing the new one, it will turn for a few seconds (If I give it a spin first).
