Genuine Daikin 165046J Run Capacitor is the 46 µF run capacitor that holds the phase shift keeping its single-phase motor turning under load once started. When it weakens the motor starts hard, runs slow, or stalls and trips the overload as current climbs. As a run capacitor is a low-cost item against the motor it protects, fitting the genuine 46 µF part is the sensible call — kept to its rated value where an under-spec generic leaves the motor straining.
