This is the factory OEM single run capacitor (part number P291-0753) designed as a direct replacement for the Carrier FA4ANF024005AFAA air handler. The run capacitor supplies a continuous phase-shifted electrical charge to the blower motor, keeping it running at peak efficiency after startup. When this capacitor fails, the blower motor may hum and refuse to start, run sluggishly, overheat, or cause the system to short-cycle — leaving you with little to no airflow and potential secondary motor damage if left unaddressed.
Compatibility: Engineered specifically for the Carrier FA4ANF024005AFAA fan coil air handler. Always cross-reference the MFD and voltage rating printed on your existing capacitor or the unit's data plate before ordering to confirm fitment. Our parts specialists are available to verify compatibility before you buy — reach out before placing your order if you have any questions.
