OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8UAA048135AAJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8UAA048135AAJA gas furnace. The blower run capacitor maintains the phase shift needed to keep the inducer or blower motor running smoothly after startup. When this capacitor weakens or fails, you'll typically notice the blower motor humming without spinning, stalling mid-cycle, or the furnace shutting down on a limit fault due to inadequate airflow. Replacing a failed run capacitor is one of the most cost-effective furnace repairs available.

• Specs: 10 MFD (microfarad) ±6% | 370V rated (370/440VAC compatible) | Oval case | 50/60 Hz | 10,000 AFC protected | Non-PCB dielectric fluid | Rated -40°C to +70°C
• OEM vs Generic: This OEM Totaline/Carrier capacitor meets exact factory tolerance (±6% MFD). Generic aftermarket units often run wider tolerances, leading to accelerated motor wear and reduced blower efficiency over time.
• Install difficulty: 1/5 — One of the simplest furnace repairs. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, and a multimeter to verify capacitance before and after. Always disconnect power at the breaker before servicing. Photograph existing wiring before removing terminals.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for the Carrier PG8UAA048135AAJA gas furnace blower motor circuit. Verify the MFD rating and voltage on your existing capacitor's label or equipment data plate before ordering to ensure correct fitment. Have questions about compatibility?
