OEM Carrier Single Run Capacitor 10 MFD 370V — P291-1003 for Model PG8UAA060155ABJA

This is the factory-specified OEM single run capacitor for the Carrier PG8UAA060155ABJA gas furnace. The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at proper speed throughout every heating cycle. When this capacitor weakens or fails, you'll notice symptoms like a sluggish blower motor that struggles to reach full speed, reduced airflow, the blower humming without starting, or the furnace shutting down on a high-limit trip caused by poor airflow and heat buildup.

• Specs: 10 MFD (microfarad) | 370V rated | Oval case | ±6% capacitance tolerance | 50/60 Hz | 10,000 AFC protected | Rated -40°C to +70°C operating temperature
• OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor manufactured to United Technologies reliability standards and tested to 60,000 service hours. Generic capacitors often carry ±10% MFD tolerance, which accelerates motor winding wear and shortens blower motor life. OEM spec ensures your motor runs at designed efficiency from day one.
• Install difficulty: 2/5 — Turn off power at the furnace disconnect and breaker before beginning. Tools needed: flathead screwdriver, needle-nose pliers, and a multimeter to verify the old capacitor is fully discharged before handling. Always photograph existing wiring before disconnecting any terminals. The oval body seats securely in the original mounting bracket with no modification required.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PG8UAA060155ABJA gas furnace blower motor circuit. Note: P291-1003 has been superseded — our stock ships the current OEM-equivalent 370/440V 10 MFD oval run capacitor, a direct drop-in replacement confirmed by Carrier. Verify the MFD rating and voltage on your unit's data plate before ordering. Have a fitment question?
