OEM Carrier Single Run Capacitor 10 MFD 370V — P291-1003 for Model PG8DAA048115ACJA

This is the factory-specified OEM single run capacitor for the Carrier PG8DAA048115ACJA gas furnace. The run capacitor provides the continuous phase-shifted current needed to keep the blower motor running efficiently after startup. When this capacitor degrades or fails, you'll notice symptoms such as a sluggish or non-starting blower motor, reduced airflow, the motor running hot to the touch, or intermittent shutdowns — all of which can trigger comfort and efficiency complaints, especially during peak heating season.

• Specs: 10 MFD (microfarad) | 370V rated (compatible to 440V) | Oval case | ±5–6% tolerance | 50/60 Hz | Non-PCB dielectric fluid | 10,000 AFC protected
• OEM vs Generic: This OEM Carrier/Totaline-sourced capacitor is manufactured to factory tolerance specifications. Generic capacitors often ship with ±10% MFD variance, which increases motor winding stress and can shorten blower motor life significantly over time.
• Install difficulty: 2/5 — Always shut off power at the breaker and discharge the capacitor terminals before handling. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, multimeter (to verify discharge). Photograph all wiring connections before removal for easy reinstallation reference.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PG8DAA048115ACJA gas furnaces. Note that Carrier sources its capacitors from third-party manufacturers — the label on the physical capacitor will reflect the supplier name (e.g., Totaline, Hartland Controls), not Carrier. This is expected and does not affect fitment or performance. Verify the 10 MFD and 370V ratings on your unit's data plate before ordering. Questions about fitment?
