The run capacitor provides a continuous phase-shifted electrical charge that keeps the blower fan motor running at proper torque and efficiency. When this capacitor weakens or fails, you'll notice the fan motor humming without spinning, running sluggishly, overheating, or tripping the system into lockout — all signs of capacitor failure that this direct OEM replacement resolves immediately.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 7.5 MFD (microfarad) | 370V rated (440V-rated replacement P291-0754 is a factory-approved upgrade) | Oval case | ±5% factory tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM capacitors are manufactured to Carrier's exact tolerance specifications. Generic alternatives frequently run outside ±10% MFD, accelerating motor winding wear and shortening blower motor life — especially critical in continuous-run air handler applications like the UPFLOW100FAUHC12.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Always discharge the capacitor fully before touching terminals. Tools needed: 1\/4\" nut driver, insulated needle-nose pliers, multimeter with capacitance setting. Photograph wiring connections before disconnecting the old unit. Note: Carrier sources capacitors from third-party manufacturers; the label on the capacitor body will reflect the OEM supplier name, not Carrier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.

Verify the 7.5 MFD rating and 370V (or higher) voltage on your unit's data plate before ordering. Note that P291-0753 has been factory-superseded by P291-0754 (440V), which is a direct drop-in upgrade. Questions about fitment?
