OEM Carrier Single Run Capacitor 15 MFD 370V — P291-1503 for Model PO8UAA048125AAJA

This is the factory-specified OEM single run capacitor for the Carrier PO8UAA048125AAJA packaged unit. The run capacitor maintains the continuous phase shift needed to keep the blower or condenser fan motor running efficiently after startup. When this component weakens or fails, you'll typically notice symptoms such as the motor humming without turning, the system struggling to start, short-cycling, or a complete no-cool / no-heat condition. Replacing it promptly protects the motor windings from overheating and extends overall system life.

• Specs: 15 MFD (microfarad) | 370V rated | Oval case | 50/60 Hz | Non-PCB dielectric fluid | UL-approved current interrupter | Multiple electrical terminals | ±5% factory tolerance
• OEM vs Generic: This is a genuine Carrier / Totaline OEM part (P291-1503), factory-matched to the PO8UAA048125AAJA's motor load specifications. Generic capacitors often carry a looser ±10% MFD tolerance, which accelerates motor winding wear and can shorten compressor or fan motor life significantly.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling terminals. Tools needed: 1/4" nut driver or 5/16" nut driver, needle-nose pliers, insulated screwdriver, multimeter (to confirm full discharge). Photograph all wiring connections before removal. Capacitors store lethal charge even after power is disconnected.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
