OEM Carrier Single Run Capacitor 15 MFD 370V for Model U19X150U60B

This OEM single run capacitor is the factory-specified replacement for the Carrier U19X150U60B, carrying Carrier/Totaline part number P291-1503. A run capacitor maintains the continuous phase shift necessary to keep the condenser fan motor spinning efficiently after startup. When this component degrades or fails, you may notice the unit struggling to start, the fan motor overheating, reduced airflow from the condenser, or the system shutting down on a high-pressure lockout. Catching a failing capacitor early prevents costly compressor and motor damage.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | Totaline / Carrier OEM-sourced
• OEM vs Generic: This OEM capacitor meets exact factory MFD and voltage tolerances. Generic aftermarket units often carry a wider ±10% tolerance, which can accelerate motor winding wear and reduce overall system lifespan — especially in high-run-time applications.
• 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 wiring connections before disconnecting the old unit for easy reference during reinstallation.
• Warranty: 1-year OEM factory warranty. Orders ship same business day from our warehouse when placed before 3 PM local time.

Compatibility note: Designed for the Carrier U19X150U60B unit. Note that P291-1503 has been superseded by updated part P291-1504 (15 MFD, 440V); verify the voltage rating on your unit's data plate before ordering to ensure correct fitment.
