Genuine Daikin T38001 Capacitor is the motor capacitor that provides the phase shift its single-phase motor needs to develop torque and run steadily under load. As it loses capacitance the motor labours to start, runs noisily, or stalls and cuts out on the overload. Since the capacitor is inexpensive against the motor that depends on it, fitting the genuine Daikin part is the easy decision — kept on its designed value where a generic substitute sits off-spec and shortens motor life.
