OEM Carrier Single Run Capacitor 10 MFD 370V for Model PG8UAA048111AAJA

This is the factory-specified OEM single run capacitor (part number P291-1003) for the Carrier PG8UAA048111AAJA packaged gas/electric unit. The run capacitor provides the sustained electrical charge the blower motor needs to start and run efficiently. When this component degrades or fails, you'll typically notice symptoms such as a humming sound with no motor movement, the blower stalling shortly after startup, reduced airflow, or the furnace/air handler failing to respond entirely. A weak or failed capacitor is one of the most common causes of blower motor failure — and replacing it early protects your motor from expensive burnout damage.

• Specs: 10 MFD (microfarad) | 370V rated (370–440V compatible) | Oval case | ±5% tolerance | 50/60Hz | Operating temp: -40°C to +70°C | Cross-references: HC91CA010D, HC91CA010, HC90AB010, HC96AC010, 97F9002
• OEM vs Generic: This OEM-specification capacitor is manufactured to Carrier's exact factory tolerance of ±5% MFD. Generic aftermarket capacitors frequently run at ±10% or wider tolerances, which can cause motor overheating, premature wear, and shortened blower motor life — a far more costly repair than the capacitor itself.
• Install difficulty: 1/5 — One of the easiest HVAC repairs. Always disconnect power and discharge the capacitor before handling. Tools needed: flathead or Phillips screwdriver, needle-nose pliers, and a multimeter to verify the old capacitor has failed. Photograph wire connections before removing terminals.
• Warranty & Shipping: 1-year OEM warranty coverage. In stock and ships same business day from our warehouse. Fast fulfillment means your system is back up and running quickly.

Compatibility: Engineered for the Carrier PG8UAA048111AAJA packaged gas/electric unit. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering to confirm an exact match. Need fitment help?
