OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA024045ACJA

This is the factory-specified OEM single run capacitor (part number P291-1003) for the Carrier PG8MAA024045ACJA packaged gas/electric unit. A single run capacitor provides the continuous phase-shifted current needed to keep a motor running efficiently after startup. When this capacitor weakens or fails, you'll notice symptoms such as a humming unit that won't fully start, a fan or blower motor that runs sluggishly, overheating motors, or the system tripping on thermal overload and short-cycling. Replacing it promptly protects the motor from burnout and restores proper system airflow and efficiency.

• Part Number & Specs: OEM Part P291-1003 | Single run capacitor | Factory-matched MFD rating and 370V/440V voltage rating — verify your unit's data plate for exact µF value before ordering.
• OEM vs Generic: This OEM unit is manufactured to Carrier's exact ±3% MFD tolerance, ensuring proper motor torque and longevity. Generic alternatives often carry ±10% tolerances, which accelerates motor winding wear and can void compressor/motor warranties.
• Install Difficulty: 2/5 — Always disconnect power and discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, insulated discharge resistor or screwdriver, multimeter. Photograph all wiring connections before removal.
