OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PY3GNA048115NA

This OEM dual run capacitor is the factory-specified replacement part (P291-7053RS) for the Carrier PY3GNA048115NA packaged unit. The dual run capacitor stores and releases the precise electrical charge required to start and sustain both the compressor and the condenser fan motor simultaneously. When this component fails, the most common symptoms include a loud humming or buzzing with no motor movement, the compressor failing to start, or the system tripping on high-pressure lockout due to a stalled fan motor — all of which leave your unit unable to cool effectively.

• Specs: 70+5 MFD (microfarad) | 370/440V dual-rated | Round case | Factory-matched ±5% tolerance | OEM Part # P291-7053RS (superseded by P291-7054R)
• OEM vs Generic: OEM capacitors are manufactured to exact factory tolerances, ensuring proper motor torque and compressor longevity. Generic aftermarket units often carry a wider ±10% MFD tolerance that can accelerate compressor wear and shorten equipment lifespan.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" nut driver, insulated needle-nose pliers, and a multimeter for post-install verification. Photograph all wiring connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty coverage. Orders ship same business day from our stocked warehouse.
