OEM Carrier Single Run Capacitor 15 MFD 370V for Model PF1MNA070000AAAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PF1MNA070000AAAA fan coil and air handler unit. The run capacitor stores and releases the precise electrical charge needed to keep the blower motor running smoothly and efficiently. When this capacitor degrades or fails, you'll notice symptoms such as the motor humming but failing to start, intermittent short-cycling, sluggish blower performance, or a complete failure to run — leaving you without conditioned air when you need it most.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | UL approved current interrupter | Non-PCB dielectric fluid | Factory-matched ±5% tolerance
• OEM vs Generic: This is the genuine Carrier/Totaline OEM capacitor (P291-1503), manufactured to exact factory tolerances. Generic aftermarket capacitors often deviate ±10% MFD, which accelerates motor winding stress and significantly shortens motor life over repeated start cycles.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings on your unit's data plate prior to installation.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed for the Carrier PF1MNA070000AAAA fan coil/air handler. Note: OEM part P291-1503 has been superseded by P291-1504 in some production runs — our team verifies current fitment before every order ships. Questions about compatibility?
