OEM Carrier Single Run Capacitor 15 MFD 370V for Model PF1MNA071000AAAA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PF1MNA071000AAAA fan coil and air handler system. The run capacitor maintains the continuous phase-shifted current required to keep the blower or condenser fan motor running efficiently after startup. A failing capacitor typically presents as a humming motor that won't spin, intermittent shutdowns, or a fan motor running slower than normal — all of which can quickly cascade into compressor or motor damage if left unaddressed.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case form factor | ±5% factory tolerance | UL recognized | RoHS compliant
• OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor built to exact factory specifications. Generic capacitors frequently ship at ±10% MFD tolerance, leading to premature motor wear, increased amp draw, and shortened equipment life — the OEM part is the only safe choice for warranty-protected systems.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wire connections before disconnecting. Replace like-for-like on MFD and voltage rating.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PF1MNA071000AAAA fan coil unit. Always verify the MFD rating and voltage stamped on your existing capacitor against your unit's data plate before ordering. Note: P291-1503 has been superseded by P291-1504 (440V-rated upgrade); both are cross-compatible replacements for this application. Have a fitment question?
