OEM Carrier Single Run Capacitor P291-1003 for Model PG8UAA048111ACJA

This OEM single run capacitor is the factory-specified replacement for the Carrier PG8UAA048111ACJA packaged gas unit. A run capacitor maintains the continuous phase-shifted current that keeps the condenser fan motor or compressor spinning efficiently after startup. When this capacitor fails, you'll typically notice symptoms such as a humming motor that won't spin, the system tripping on thermal overload, hard-starting compressors, or the unit shutting down shortly after turning on — all classic signs of capacitor failure in a packaged unit.

• Specs: Single run capacitor | OEM Part Number P291-1003 | Factory-matched MFD and voltage rating | Round or oval case per OEM specification | Meets or exceeds original factory tolerances of ±3%
• OEM vs Generic: This is a genuine OEM Carrier capacitor — factory-matched to the exact MFD and voltage required by the PG8UAA048111ACJA. Generic capacitors commonly run ±10% MFD tolerance, which accelerates motor winding wear, shortens compressor life, and can void equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify capacitance. Photograph all wire connections before removal. This is a common DIY repair for a trained homeowner or service technician.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff time.

Compatibility: Designed as a direct OEM replacement for Carrier model PG8UAA048111ACJA packaged gas units (4-ton, 111,000 BTU). Always verify the MFD and voltage rating printed on your existing capacitor against your unit's data plate before ordering to ensure a perfect fit. Have questions about fitment?
