OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8JAA066135ABJA

This is the factory-specified OEM single run capacitor for the Carrier PG8JAA066135ABJA gas furnace. The run capacitor provides the continuous phase-shifted electrical charge that keeps the blower motor spinning at rated speed. When this capacitor degrades or fails, the blower motor may hum without starting, run sluggishly, draw excessive amperage, or trip its thermal overload — leaving you with no airflow and a furnace that locks out on a high-limit fault. Replacing this capacitor is one of the most cost-effective repairs in HVAC service.

• Specs: 10 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | 50/60 Hz | Operating temp: -40°C to +70°C | Non-PCB construction | Part # P291-1003 (superseded by P291-1004)
• OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact tolerance specification by Totaline/Hartland Controls. Generic alternatives often carry a ±10% MFD tolerance, which shortens motor winding life and can cause premature blower motor failure — costing far more than the capacitor itself.
• Install Difficulty: 2/5 — Discharge the capacitor before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph existing wiring before disconnecting. Typical replacement time: 15–20 minutes.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.
