OEM Carrier Single Run Capacitor 15 MFD 370V — P291-1503 for Model PH1PEA036000AABA

This OEM single run capacitor is the factory-specified replacement part P291-1503 for the Carrier PH1PEA036000AABA heat pump system. The run capacitor provides the sustained phase-shifted electrical charge required to keep the condenser fan motor or compressor motor spinning efficiently during operation. When a run capacitor weakens or fails, you'll typically experience symptoms such as a humming motor that won't start, the unit short-cycling within minutes of startup, higher-than-normal energy consumption, or complete failure of the condenser fan or compressor to run at all. Replacing the capacitor promptly prevents secondary damage to the motor windings.

• 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 OEM-specification capacitor matched to Carrier's factory tolerance requirements. Generic capacitors frequently run at ±10% MFD deviation, which accelerates motor winding stress and can shorten compressor life significantly over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals (use a 20kΩ resistor or insulated screwdriver). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode recommended). Photograph all wiring connections before disconnecting the old capacitor.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PH1PEA036000AABA heat pump systems. Note: P291-1503 has been superseded — verify the MFD rating and voltage on your unit's data plate before ordering to ensure correct fitment. Our team is available to confirm compatibility before you purchase.
