OEM Carrier Single Run Capacitor P291-1503 for Model PG8JAA036045ADJA

This OEM single run capacitor (part number P291-1503) is the factory-specified replacement for the Carrier PG8JAA036045ADJA packaged gas/electric unit. The run capacitor provides the continuous phase-shifted voltage needed to keep the blower or condenser fan motor running efficiently after startup. When this capacitor degrades or fails, symptoms include a humming motor that won't spin, intermittent shutdowns, overheating, or a complete no-start condition on the affected motor circuit.

• Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Cylindrical case | ±5% tolerance per OEM specification — verify exact MFD on your unit's data plate
• OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory tolerances. Aftermarket/generic capacitors frequently carry ±10% MFD variance, which accelerates motor winding wear, reduces efficiency, and can void equipment warranties.
• Install Difficulty: 2/5 — Single run capacitors are among the most straightforward HVAC repairs. Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting terminals.
• Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship the same business day from our warehouse.

Compatibility: Designed for the Carrier PG8JAA036045ADJA packaged gas/electric unit. Always cross-reference the MFD and voltage rating on your existing capacitor and equipment data plate before ordering to confirm fitment. Our HVAC parts specialists are available to verify compatibility before you buy — same-day shipping on all stocked orders.
