OEM Carrier Single Run Capacitor 10 MFD 370V — P291-1003 for Model PG8UAA048091ACJA

This OEM Carrier single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8UAA048091ACJA gas furnace. The run capacitor maintains a continuous phase-shifted current to keep the blower motor spinning at rated speed throughout every heating cycle. When it degrades or fails, the blower motor may hum without starting, run sluggishly, overheat, or stall entirely — reducing airflow, triggering limit switches, and ultimately causing furnace lockout. Replacing this low-cost component proactively is one of the most effective preventive maintenance steps you can take on any Carrier furnace.

• Specs: 10 MFD (microfarad) ±6% | 370V rated | Oval case | 50/60 Hz | Non-PCB castor oil dielectric | UL-approved current interrupter | Multiple electrical terminals | –40°C to +70°C operating range
• OEM vs Generic: This is the genuine Carrier-branded (Totaline) capacitor built to factory ±6% MFD tolerance. Off-brand generic capacitors often ship at ±10% or worse, causing the blower motor to run hotter and shortening its service life. OEM match means zero guesswork on fitment.
• Install difficulty: 1/5 — One of the easiest furnace repairs available. Tools needed: flathead or Torx screwdriver (access panel), needle-nose pliers, multimeter (recommended to confirm capacitor failure before ordering). Always discharge the capacitor before handling and photograph wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PG8UAA048091ACJA. Note: Carrier sources capacitors from third-party manufacturers — the label on the capacitor will reflect the component manufacturer's name (e.g., Totaline/Hartland Controls), not Carrier. This is normal and does not affect fitment or warranty. Verify the 10 MFD and 370V ratings on your unit's data plate before ordering. Have a fitment question? Our HVAC parts specialists verify compatibility before you buy — order with confidence.
