OEM Carrier Single Run Capacitor P291-1003 for Model PG8MAA048110ABJA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA048110ABJA packaged gas/electric unit. The run capacitor provides the continuous phase-shifted current necessary to keep the blower or condenser fan motor running at peak efficiency. When this capacitor degrades or fails, you'll typically notice symptoms such as the motor humming without spinning, the system short-cycling due to thermal overload, sluggish motor startup, or a complete motor no-start condition — all of which can rapidly escalate to full motor burnout if left unaddressed.

• Specs: Single run capacitor | Factory OEM-matched MFD rating | 370V/440V rated | Cylindrical case | Tight ±3% capacitance tolerance for optimal motor performance
• OEM vs Generic: This is a genuine OEM Carrier part (P291-1003), manufactured to exact factory specifications. Generic aftermarket capacitors typically carry a loose ±10% MFD tolerance, which accelerates motor winding stress, increases heat buildup, and significantly shortens motor life — costing far more in the long run.
• Install Difficulty: 2/5 — A straightforward single-capacitor swap suitable for experienced DIYers and technicians. Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting terminals.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for the Carrier PG8MAA048110ABJA packaged unit. Always verify the MFD rating and voltage stamped on your existing capacitor's label against your unit's data plate before ordering. Not sure it fits?
