OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA060090ABJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA060090ABJA gas furnace. The run capacitor provides a continuous phase-shifted current to keep the blower motor running at peak efficiency once it has started. When this capacitor begins to fail, you'll notice symptoms such as a slow-starting blower, an audible hum with no motor movement, intermittent blower operation, or the furnace shutting down on a high-limit trip caused by insufficient airflow. Replacing a failed run capacitor is one of the most cost-effective furnace repairs available.

• Specs: 10 MFD (microfarad) | 370–440V rated | Oval case | ±5% tolerance | 50/60 Hz | 10,000 AFC protected | Non-PCB construction | Operating temp: -40°C to +70°C
• OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to exact factory tolerances. Generic capacitors often ship at ±10% MFD tolerance, which accelerates motor winding wear and shortens blower motor service life — a far costlier repair than the capacitor itself.
• Install difficulty: 2/5 — A straightforward repair for a confident DIYer. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (capacitance setting). Always discharge the capacitor fully before touching terminals, and photograph all wiring connections before removal.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
