OEM Carrier Single Run Capacitor for Model PY3PEA042060AA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY3PEA042060AA packaged unit. A single run capacitor maintains a continuous phase-shifted current to keep either the compressor motor or the fan motor running at peak efficiency after startup. When this capacitor fails, the motor it supports will hum without turning over, draw excessive amperage, overheat, and ultimately trip on thermal overload — or the unit will short-cycle within the first few minutes of operation.

• OEM Part Numbers: P291-0403 and P291-1503 — both are factory-authorized single run capacitors for this model. Verify the MFD rating and voltage on your unit's data plate before ordering to confirm which applies to your specific configuration.
• OEM vs Generic: OEM capacitors are manufactured to exact factory tolerances (±3% MFD). Generic aftermarket capacitors often carry a ±10% tolerance, which accelerates motor winding wear, shortens compressor life, and can void equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter capable of capacitance measurement. Photograph all wiring connections prior to removal.
• Warranty: 1-year OEM factory warranty. In-stock and ships the same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PEA042060AA packaged unit. Cross-reference your existing capacitor's MFD rating and voltage stamped on the label to confirm fitment between P291-0403 and P291-1503. Our parts specialists are available to verify compatibility before you order — no guesswork required.
