This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier FC4BNF060000AAAA fan coil unit. The run capacitor provides the continuous phase-shifted current needed to keep the blower motor running efficiently at rated speed. When this capacitor degrades or fails, common symptoms include a humming motor that won't start, sluggish blower performance, intermittent shutdowns, or a complete loss of airflow — often accompanied by overheating of the motor windings.
Compatibility: Designed specifically for the Carrier FC4BNF060000AAAA fan coil unit. Always verify the MFD and voltage rating printed on your existing capacitor or the unit's data plate before ordering to ensure a correct match. Not sure if this part fits your system?
