OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PY3GNA048130AA

This OEM dual run capacitor (part number P291-7053RS) is the factory-specified replacement for Carrier PY3GNA048130AA packaged HVAC systems. The dual run capacitor simultaneously serves both the compressor and the condenser fan motor — storing and releasing the precise electrical charge needed to start and sustain operation. When this capacitor fails, you'll typically notice a loud hum with no motor startup, intermittent short-cycling, or a condenser fan that spins slowly or not at all. Left unaddressed, a weak or failed capacitor can cause the compressor to overheat and fail prematurely — making timely replacement critical.

• Specs: 70+5 MFD (microfarad) | 370/440V dual-rated | Round case | Factory-matched ±5% tolerance | Replaces OEM part P291-7053RS (superseded by P291-7054R)
• OEM vs Generic: OEM capacitors are manufactured to Carrier's exact factory tolerances. Generic aftermarket units often drift ±10% MFD over time, increasing stress on the compressor and fan motor windings and significantly shortening equipment life.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching terminals (use a 20,000-ohm resistor or insulated screwdriver). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (for capacitance verification). Photograph all wiring before disconnecting. Turn off power at both the thermostat and the disconnect box before beginning.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse — order by 3 PM for guaranteed same-day dispatch.

Compatibility: Engineered as a direct OEM replacement for Carrier model PY3GNA048130AA. Also cross-references Carrier/Bryant/Payne part numbers P291-7053R and P291-7054R, and GE/Genteq part numbers C3705R and 27L633. Always verify the MFD ratings and voltage on your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment before you buy — no guesswork required.
