OEM Carrier Dual Run Capacitor 35+5 MFD 440V for Model PY2PNB024060NB

This OEM capacitor kit contains all factory-specified run capacitors for the Carrier PY2PNB024060NB condenser system. The dual run capacitor (P291-3553 / superseded by P291-3554RS) serves both the compressor and condenser fan motor simultaneously, while the single run capacitors (P291-0403 and P291-1503) support individual motor circuits. When any of these capacitors fail, you'll typically notice the system humming without starting, blowing warm air, short-cycling, or the condenser fan failing to spin — all classic signs that the stored charge needed to start and sustain motor operation has degraded below factory tolerance.

• Specs (Primary — P291-3553 Dual Run): 35+5 MFD (microfarad) | 440V rated | Round case | ±6% factory tolerance | 50/60 Hz | 10,000 AFC rated | RoHS compliant | Castor oil protected, No PCBs
• OEM vs Generic: Genuine Carrier OEM capacitors are performance-tested to meet United Technologies reliability requirements for capacitance ratings, power factor, and dissipation factor. Generic aftermarket units often run ±10% MFD tolerance, accelerating compressor and fan motor wear over time.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter with capacitance function. Photograph all wiring before disconnecting — the dual cap terminals are labeled HERM (compressor), FAN, and C (common).
• Warranty & Shipping: 1-year OEM factory warranty. In stock and ships same business day from our warehouse. Free shipping on orders over $99.

Compatibility: Engineered as a direct OEM drop-in replacement for Carrier model PY2PNB024060NB. This listing covers all three factory capacitor part numbers for this unit: dual run capacitor P291-3553 (primary, superseded by P291-3554RS), and single run capacitors P291-0403 and P291-1503. Always verify MFD rating and voltage against your unit's data plate before ordering. Not sure which capacitor you need? Our HVAC parts specialists verify fitment before you buy — contact us today.
