OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8MAA048135ADJA

This is the factory-specified OEM single run capacitor (part number P291-1003) for the Carrier PG8MAA048135ADJA gas furnace. The run capacitor sustains the electrical charge that keeps the indoor blower motor spinning at rated speed. When this component weakens or fails, the blower motor struggles to reach full RPM — symptoms include an audible hum with no airflow, a motor that stalls shortly after startup, or a furnace that trips on high-limit due to insufficient airflow across the heat exchanger.

• Specs: 10 MFD (microfarad) | 370V rated | Oval case form factor | ±5% tolerance | 50/60 Hz | Operating temp: -40°C to +70°C | Non-PCB design
• OEM vs Generic: This OEM Carrier capacitor is manufactured to exact factory tolerances, ensuring the blower motor receives the precise electrical support it was designed for. Generic aftermarket capacitors often carry wider MFD tolerances (±10%), which can cause premature motor wear and reduce blower motor lifespan.
• Install difficulty: 1/5 — One of the simplest HVAC repairs available. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, and a multimeter to confirm the old capacitor has discharged before handling. Always photograph the existing wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before 3PM ship same business day from our warehouse.

Compatibility: Designed for the Carrier PG8MAA048135ADJA gas furnace. Always verify the MFD rating and voltage on your unit's data plate or existing capacitor before ordering to ensure a correct fit.
