OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8JAA048135ADJA

This OEM single run capacitor (P291-1003 / superseded by P291-1004) is the factory-specified replacement for the Carrier PG8JAA048135ADJA packaged gas furnace. The run capacitor maintains a continuous phase-shifted current to the blower motor's start winding, keeping it spinning efficiently throughout every heating and cooling cycle. When this capacitor weakens or fails, you'll notice symptoms like a sluggish or humming blower motor that won't start, intermittent airflow loss, blower motor overheating, or a furnace that locks out due to insufficient airflow across the heat exchanger.

• Specs: 10 MFD (microfarad) | 370V rated (440V-rated successor P291-1004 is a direct drop-in) | Oval case | Factory ±5% capacitance tolerance | 50/60 Hz | Operating temp: -40°C to +70°C
• OEM vs Generic: This is a genuine Carrier/Totaline-sourced capacitor, reliability-tested to 60,000 service hours per UTC application parameters. Generic capacitors often deviate significantly from rated MFD, causing motor winding stress and premature failure.
• Install difficulty: 2/5 — Shut off power at the disconnect before touching any terminals. Discharge the old capacitor across its terminals with an insulated screwdriver before removal. Tools needed: flathead screwdriver, 1/4" nut driver, needle-nose pliers. Always photograph existing wiring before disconnecting. Typical replacement time: under 15 minutes.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the factory replacement for Carrier model PG8JAA048135ADJA. Note: OEM part P291-1003 has been superseded — current fulfillment ships as P291-1004 (440V, 10 MFD), a direct upgrade. Always verify MFD rating and voltage on your unit's data plate before ordering.
