OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PY4GNAA48130AA

This OEM dual run capacitor (part number P291-7053RS) is the factory-specified replacement for the Carrier PY4GNAA48130AA split-system air conditioner. The dual run capacitor simultaneously supports both the compressor and the condenser fan motor — storing and releasing the precise electrical charge needed to start and sustain operation. When this component fails, symptoms typically include a loud hum with no compressor or fan startup, the system short-cycling within the first few minutes of operation, or the condenser fan spinning slowly or not at all. Ignoring a failing capacitor puts excessive strain on the compressor, risking a far more costly repair.

• Specs: 70+5 MFD (microfarad) | 370/440V rated | Round case | Factory-matched ±5% tolerance | Replaces P291-7053RS, P291-7053R, C3705R, 27L633
• OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances, ensuring proper motor ramp-up and sustained run performance. Generic aftermarket units commonly ship with ±10% MFD variance, which accelerates compressor wear and can shorten system lifespan significantly.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal. Note: 440V-rated capacitors are a safe upgrade for 370V applications.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our climate-controlled warehouse.

Compatibility: Designed for Carrier model PY4GNAA48130AA. Also cross-references Bryant and Payne units sharing the same capacitor specification. Always verify the MFD rating and voltage on your unit's data plate before ordering. Our HVAC parts specialists are available to confirm fitment — order with confidence.
