OEM Carrier Single Run Capacitor 10 MFD 370/440V for Model PG8JAA048110ABJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8JAA048110ABJA gas furnace. The run capacitor supports the blower motor by maintaining the phase-shifted current needed to keep it spinning efficiently after startup. When this capacitor weakens or fails, you'll typically notice reduced airflow, a humming blower that struggles to reach full speed, intermittent shutdowns, or a motor that fails to start altogether — leaving you without conditioned air when you need it most.

• Specs: 10 MFD (microfarad) | 370/440V dual-rated | Oval case | Factory-matched ±5% tolerance for precise motor protection
• OEM vs Generic: This is a genuine Carrier OEM part (P291-1003 / superseded by P291-1004), manufactured to exact factory specifications. Generic capacitors often carry wider MFD tolerances, which can accelerate motor winding wear and shorten blower motor life.
• Install difficulty: 1/5 — One of the easiest HVAC repairs available. Tools needed: flat-head screwdriver, needle-nose pliers, and a multimeter to verify discharge before removal. Always discharge the old capacitor fully before handling, and photograph terminal wiring prior to disconnecting.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PG8JAA048110ABJA gas furnace blower circuit. Note that Carrier sources capacitors from approved third-party manufacturers — the label on the capacitor body will reflect the component manufacturer's name, not Carrier's. Always verify the MFD rating and voltage on your unit's data plate before ordering. Have a fitment question? Our parts team confirms compatibility before you buy.
