OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PPB060130AB

This is the genuine OEM single run capacitor for the Carrier PY2PPB060130AB packaged HVAC unit. The run capacitor stays in the circuit continuously during motor operation, storing and releasing electrical energy to keep the condenser fan motor or blower running efficiently. When this capacitor fails, you'll typically notice the system humming without starting, blowing warm air, or short-cycling — all signs of a motor that can no longer sustain proper voltage. This listing covers OEM part numbers P291-0403 (primary), P291-1003, and P291-2503 — the factory-specified single run capacitors used across this unit's motor circuits.

• Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | Factory ±6% tolerance | Replaces OEM P/N 97F5704
• OEM vs Generic: Genuine Carrier OEM capacitors are manufactured to exact factory tolerance specifications. Aftermarket substitutes often carry a wider ±10% MFD variance, which accelerates motor winding wear and shortens equipment life — especially critical in continuously-running packaged units.
• Install difficulty: 2/5 — Discharge the capacitor fully before touching any terminals (use an insulated resistor or multimeter set to capacitance mode). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Always photograph existing wiring connections before disconnecting any terminals.
• Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PY2PPB060130AB packaged gas/electric unit. Three OEM part numbers — P291-0403, P291-1003, and P291-2503 — cover distinct motor circuit capacitor positions on this model. Verify the MFD rating stamped on your existing capacitor's label against the part number before ordering. Not sure which you need? Our fitment team confirms compatibility before your order ships.
