OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PY3GNA048130NA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY3GNA048130NA packaged unit, sourced under OEM part number P291-7053RS (current successor: P291-7054R). The dual run capacitor stores and releases the precise electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. When this component fails, you'll typically hear the unit hum without the compressor or fan spinning up, experience repeated short-cycling, or notice the system tripping on thermal overload — all signs of a capacitor that can no longer hold its rated charge.

• Specs: 70+5 MFD (microfarad) | 440V rated (370V compatible) | Round case | Factory-matched ±3% tolerance | CBB65 style
• OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances, ensuring proper motor starting torque and runtime efficiency. Generic aftermarket units often drift ±10% MFD, which accelerates compressor wear, shortens motor life, and can void equipment warranties.
• Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all terminal wiring before disconnecting. Replace only with the engine off and power locked out at the disconnect.
• Warranty & Shipping: 1-year OEM manufacturer warranty. In stock and ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Engineered for the Carrier PY3GNA048130NA packaged unit. Also cross-references Carrier/Bryant/Payne part numbers P291-7053R and GE/Genteq equivalents C3705R and 27L633. Always verify the MFD rating and voltage on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — contact us anytime.
