OEM Carrier Dual Run Capacitor 35+5 MFD 370V for Model PY2PNB024060AB

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY2PNB024060AB packaged heat pump unit, cross-referencing OEM part numbers P291-3553 (primary), P291-0403, and P291-1503. The dual run capacitor stores and releases the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously in a single round case. When this capacitor degrades or fails, symptoms include a loud hum with no motor movement, the compressor or fan spinning sluggishly, the system short-cycling, or a complete no-start condition — often on the hottest day of the year.

• Specs: 35+5 MFD (microfarad) | 370V rated | Round case | HERM / C / FAN terminals | Factory ±3% tolerance | Replaces P291-3553, P291-0403, P291-1503
• OEM vs Generic: OEM Carrier capacitors are manufactured to exact factory tolerances. Generic alternatives commonly run ±10% MFD, which stresses the compressor windings and condenser fan motor over time — accelerating wear and shortening equipment life.
• 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 setting. Always photograph all wiring connections before disconnecting. Match terminal labels: HERM (compressor), FAN (condenser fan motor), C (common).
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse in original manufacturer packaging.

Compatibility: Engineered for the Carrier PY2PNB024060AB packaged heat pump unit. Always verify the MFD rating and voltage on your unit's data plate before ordering — using an incorrect MFD value can damage the compressor or fan motor. Have questions about fitment?
