OEM Carrier Single Run Capacitor for Model PY3PPA042060AA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY3PPA042060AA residential packaged or split-system unit. The run capacitor maintains a continuous phase-shifted current to keep the compressor or fan motor spinning at rated efficiency. When the capacitor degrades or fails, you'll notice symptoms like a humming compressor that won't start, intermittent short-cycling, a hot outdoor unit that shuts down quickly, or a complete no-cool condition — even with the thermostat calling for cooling.

• Specs: Single run capacitor | Matches OEM MFD and voltage rating for PY3PPA042060AA | Factory-matched ±5% tolerance | Replaces OEM part numbers P291-0403 and P291-1503
• OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory specifications. Aftermarket capacitors often carry a wider ±10% MFD tolerance, which can accelerate motor and compressor wear over time, reducing system lifespan.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter (to verify discharge and confirm capacitance). Photograph all wiring before disconnecting terminals.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PPA042060AA. Always verify the MFD rating and voltage stamped on your existing capacitor's label or the unit's data plate before ordering to confirm fitment. Have questions about compatibility?
