OEM Carrier Single Run Capacitor 15 MFD 370V for Model UPFLOW175U6019X

This OEM single run capacitor is the factory-specified replacement part P291-1503 for the Carrier UPFLOW175U6019X air handler and upflow system. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running efficiently at full speed. When the capacitor degrades or fails, you'll notice symptoms such as a humming motor that won't spin up, the system short-cycling within the first few minutes of operation, reduced airflow, or a blower motor that runs hot and eventually trips on thermal overload.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | Totaline / Carrier OEM part number P291-1503
• OEM vs Generic: This is an OEM-grade capacitor matched to Carrier's exact factory specifications. Generic capacitors often carry a wider ±10% MFD tolerance, which accelerates motor winding wear and shortens the service life of your blower motor.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead and Phillips screwdriver, needle-nose pliers, multimeter (to verify discharge and confirm MFD). Photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Designed for use in the Carrier UPFLOW175U6019X upflow air handler. Always verify the MFD rating and voltage on your unit's data plate before ordering. Note: P291-1503 has been superseded — our listing ensures you receive the correct factory-spec capacitor. Contact our fitment team with any questions before you order.
