OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA024045AAJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8MAA024045AAJA gas furnace blower motor circuit. The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at correct speed and torque. When it degrades or fails, you'll notice symptoms like a sluggish or humming blower motor that struggles to start, reduced airflow, motor overheating, or a furnace that trips on thermal overload shortly after ignition. Replacing this low-cost part promptly protects the far more expensive blower motor from burnout.

• Specs: 10 MFD (microfarad) | 370V rated | Oval case form factor | ±6% tolerance | 50/60 Hz | Non-PCB dielectric fluid | 10,000 AFC protected | Operating temp: -40°C to +70°C
• OEM vs Generic: This is a genuine Carrier/Totaline-sourced capacitor manufactured to exact factory specifications. Generic capacitors often carry wider MFD tolerances (±10% or more), which accelerates motor winding wear and shortens blower motor life — especially in a continuously running furnace application.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Discharge the capacitor terminals before touching (use an insulated screwdriver across the terminals). Tools needed: flathead screwdriver, needle-nose pliers, multimeter (to verify old cap is bad). Always photograph the existing wiring before disconnecting. No refrigerant handling required.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PG8MAA024045AAJA gas furnace blower motor circuit. OEM part number P291-1003 (Totaline/Carrier); superseded by P291-1004 (440V-rated upgrade — a direct, compatible replacement). Always confirm the MFD rating on your existing capacitor's label before ordering. Have a question about fitment?
