OEM Carrier Single Run Capacitor 10 MFD 370V — P291-1003 for Model PG8MAA060090ADJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8MAA060090ADJA gas furnace. The run capacitor supplies the continuous phase-shifted current that keeps the blower motor spinning at the correct speed and torque. When this capacitor weakens or fails, you'll typically notice the blower motor humming without starting, running sluggishly, overheating, or tripping the motor's thermal overload — all classic signs of a capacitor that can no longer hold its rated charge.

• Specs: 10 MFD (microfarad) | 370V rated (440V compatible) | Oval case | ±5% factory tolerance | 50/60 Hz | AFC 10,000 | Non-PCB dielectric fluid | OEM Part # P291-1003 (superseded by P291-1004)
• OEM vs Generic: This is a factory-authorized OEM part manufactured to Carrier's exact tolerances. Generic capacitors often carry a wider ±10% MFD tolerance, which accelerates motor winding wear and shortens blower motor life — especially in a high-cycle furnace application.
• Install difficulty: 2/5 — Always shut off power at the breaker and discharge the capacitor before handling. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (to verify residual charge is zero). Photograph all terminal connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered for Carrier model PG8MAA060090ADJA gas furnaces. Note that P291-1003 has been superseded by OEM part P291-1004 — both are 10 MFD, 370/440V oval run capacitors and are functionally interchangeable. Always verify the MFD rating and voltage on your unit's data plate before ordering. Have questions about fitment?
