OEM Carrier Single Run Capacitor P291-1003 for Model PG8JAA048110AAJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8JAA048110AAJA packaged gas heating and electric cooling unit. The run capacitor maintains a continuous phase-shifted current to keep the blower or condenser fan motor running at peak efficiency after startup. When it fails, the motor may hum and fail to start, draw excessive amperage, overheat, or cause the system to short-cycle — leaving your customers without heat or cooling.

• Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Round case | OEM ±3% tolerance for precise motor performance
• OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory tolerances. Generic aftermarket capacitors commonly carry a ±10% MFD variance, which accelerates motor winding wear, shortens equipment life, and can void equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed specifically for the Carrier PG8JAA048110AAJA packaged gas/electric unit. Always verify the MFD rating and voltage against your unit's data plate before ordering.
