OEM Carrier Single Run Capacitor 40 MFD 370V for Model PG9YAA060100ACSS

This OEM single run capacitor is the factory-specified replacement for the Carrier PG9YAA060100ACSS gas furnace. The run capacitor provides the sustained phase-shifted current that keeps the blower motor spinning at correct speed and efficiency. When the capacitor degrades or fails, you'll typically notice the blower motor humming without starting, the system shutting down on high-limit due to poor airflow, or sluggish motor ramp-up that causes erratic heating cycles.

• Specs: 40 MFD (microfarad) | 370V AC rated | Single run, oval case | ±5% factory tolerance | 50/60 Hz | OEM Part Number: P291-4003
• OEM vs Generic: This OEM-spec capacitor is manufactured to Carrier's exact tolerance and dielectric standards. Generic aftermarket capacitors frequently run at ±10% MFD deviation, placing excess stress on motor windings and shortening blower motor life — a far more expensive repair.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: flathead or 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Verify MFD and voltage ratings match your unit's data plate exactly.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse via FedEx or UPS Ground.

Compatibility: Engineered as a direct OEM replacement for Carrier model PG9YAA060100ACSS. Always cross-reference the MFD and voltage rating on your existing capacitor or unit data plate prior to ordering. Have a fitment question?
