OEM Carrier Single Run Capacitor 15 MFD 370V for Model PF1MNA048000AAAA

This is the factory-specified OEM single run capacitor (P291-1503) for the Carrier PF1MNA048000AAAA fan coil and associated HVAC equipment. The run capacitor maintains the continuous phase-shifted current needed to keep the motor running at rated torque and efficiency. When this capacitor weakens or fails, you'll notice symptoms such as a humming condenser with no motor start, intermittent short-cycling, reduced airflow, compressor overheating, or a tripped high-pressure limit. Replacing it promptly prevents costly secondary damage to the motor windings or compressor.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | ±5% factory tolerance | Multiple electrical terminals
• OEM vs Generic: This is the genuine Carrier/Totaline OEM part, sourced through authorized distribution channels. Generic capacitors commonly run ±10% MFD tolerance, which accelerates motor wear and may void compressor warranties. The OEM unit is factory-matched for exact fit and electrical spec.
• Install difficulty: 2/5 — Always discharge the capacitor before handling — stored charge can cause serious injury. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Typical replacement time: 15–20 minutes.
• Warranty: 1-year OEM manufacturer warranty. Orders placed before cutoff ship same business day from our stocked warehouse.
