OEM Carrier Single Run Capacitor 15 MFD 370V for Model PF1MNC048000AAAA

This OEM single run capacitor is the factory-specified replacement for the Carrier PF1MNC048000AAAA air handler. Rated at 15 MFD at 370 volts, this oval-style capacitor maintains the steady electrical charge required to keep the blower or condenser fan motor running at peak efficiency. When the run capacitor fails, you'll typically notice symptoms such as a humming motor that won't spin up, intermittent short-cycling, reduced airflow, or the system tripping on thermal overload shortly after startup. Replacing it promptly prevents cascading damage to the motor windings.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | Multiple electrical terminals
• OEM vs Generic: This is the genuine Carrier/Totaline OEM part (P291-1503), manufactured to exact factory MFD tolerances of ±5%. Generic capacitors often carry a ±10% tolerance, which can accelerate motor wear and shorten equipment life over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (for capacitance verification). Photograph all wiring connections before removal. Disconnect power at the breaker before starting.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse — get your system back online fast.

Compatibility: Designed for the Carrier PF1MNC048000AAAA air handler. Verify the MFD rating and voltage on your unit's data plate before ordering to ensure correct fitment. Note: Carrier sources capacitors from third-party manufacturers — the label on the capacitor body may reflect the sub-manufacturer's name rather than Carrier. Questions about fitment? Our HVAC parts specialists verify compatibility before you buy.
