OEM Carrier Single Run Capacitor P291-1503 for Model PH3PEA036000AA

This is the factory-specified OEM single run capacitor for the Carrier PH3PEA036000AA packaged heat pump unit. A single run capacitor provides the sustained electrical charge required to keep the compressor or fan motor running at peak efficiency. When this capacitor degrades or fails, common symptoms include a humming sound with no motor movement, the system tripping on high-pressure lockout, hard-start conditions, or the unit short-cycling shortly after startup. Replacing it with the correct OEM part ensures factory-matched performance and protects downstream components.

• Specs: OEM Part Number P291-1503 | Single run capacitor | Factory-matched MFD and voltage rating | Engineered to exact factory tolerance (±5%) for the Carrier PH3PEA036000AA
• OEM vs Generic: This OEM unit is manufactured to Carrier's exact electrical specifications. Generic alternatives frequently carry wider MFD tolerances (±10–15%), which can stress motor windings, reduce efficiency, and shorten the service life of your compressor or fan motor.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify capacitance after installation. Photograph all wiring connections prior to removal.
