This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier FA4ANC036008AAAA fan coil air handler. The run capacitor maintains a continuous phase-shifted electrical charge to keep the blower motor running at peak efficiency. When this component fails, you'll typically notice the blower motor humming but not spinning, the system short-cycling, or the air handler failing to move conditioned air altogether — even while the compressor runs normally at the outdoor unit.
Compatibility: Designed specifically for the Carrier FA4ANC036008AAAA fan coil air handler. Always verify the MFD rating and voltage printed on your existing capacitor or the unit's data plate before ordering to confirm an exact match. Not sure?
