OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PY3GNA048115AA

This OEM dual run capacitor (part number P291-7053RS) is the factory-specified replacement for the Carrier PY3GNA048115AA split-system air conditioner. The dual run capacitor simultaneously supports both the compressor and the condenser fan motor — storing and discharging the electrical energy needed to start and sustain each motor through the full operating cycle. When this capacitor weakens or fails, the most common symptoms are a loud humming or buzzing with no compressor start, a condenser fan that spins slowly or not at all, the system short-cycling within minutes of startup, or a tripped breaker from motor overload. Left unaddressed, a failed capacitor will rapidly overheat and permanently damage the compressor — making timely replacement critical.

• Specs: 70+5 MFD (microfarad) | 370/440V dual-rated | Round case | Factory ±3% MFD tolerance | OEM part number P291-7053RS (superseded by P291-7054R)
• OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances, ensuring proper motor starting torque and run efficiency. Generic aftermarket units often carry a ±10% MFD tolerance, which accelerates motor bearing wear and can shorten compressor life significantly over time.
• Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use an insulated screwdriver across each terminal pair). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. The entire swap typically takes under 20 minutes.
• Warranty & Shipping: 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model PY3GNA048115AA. Note that OEM part P291-7053RS has been superseded by updated part number P291-7054R — both are functionally identical at 70+5 MFD 370/440V. Always verify the MFD rating and voltage stamped on your existing capacitor's label before ordering.
