OEM Carrier Single Run Capacitor (P291-0403 / P291-2503) for Model PY3PPA060115AA

This factory-original single run capacitor is the OEM-specified replacement for the Carrier PY3PPA060115AA 5-ton packaged gas/electric rooftop unit. A single run capacitor maintains the steady electrical charge required to keep the compressor or condenser fan motor running efficiently after startup. When this component weakens or fails, you'll notice symptoms such as hard starting, audible humming with no motor rotation, the system tripping on high pressure, or the unit short-cycling — all signs of capacitor degradation that worsen rapidly in summer heat loads.

• OEM Part Numbers: P291-0403 (primary) | P291-2503 (alternate/superseded) — both are direct factory replacements for the Carrier PY3PPA060115AA packaged rooftop unit. Always verify MFD and voltage ratings on your unit's data plate before ordering.
• OEM vs Generic: This is a genuine Carrier OEM capacitor held to factory-specified MFD tolerance (±3%). Aftermarket generics often run ±10% tolerance, which increases motor winding stress, accelerates compressor wear, and can void your equipment warranty.
• Install Difficulty: 2/5 — Disconnect and lock out power before servicing. Discharge the capacitor fully using an insulated resistor or discharge tool before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Photograph all wiring connections before removal.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your unit back online fast.

Compatibility: Designed and factory-matched for the Carrier PY3PPA060115AA 5-ton packaged gas/electric rooftop unit. Cross-references OEM part numbers P291-0403 and P291-2503. Confirm capacitor MFD rating and voltage stamped on your existing unit's data plate before completing your order. Have a fitment question?
