When the switch is first closed, the voltage across the capacitor (which we were told was fully discharged) is zero volts; thus, it first behaves as though it were a short-circuit. Over time, the capacitor voltage will rise to equal battery voltage, ending in a condition where the capacitor behaves as an open-circuit.
Designed for momentary use, the start capacitor disconnects from the motor after it starts to prevent damage. If your air conditioner is not turning on, or is taking a lot longer to get up to full speed, then a new start capacitor is probably what you need. In hot environments, this capacitor may be over worked and fail prematurely. At this point, a replacement will need to be obtained to bring the system back online.
