OEM Carrier Dual Run Capacitor 70+5 MFD 370/440V for Model PY4GNAA48090AA

This OEM dual run capacitor (part number P291-7053RS) is the factory-specified replacement for the Carrier PY4GNAA48090AA packaged unit. The dual run capacitor simultaneously supports both the compressor and the condenser fan motor — storing and releasing the electrical charge needed to start each component and keep them running efficiently. When this capacitor fails, common symptoms include a loud humming with no motor movement, a system that trips on high-pressure lockout, short-cycling within the first few minutes of operation, or a condenser fan that spins only when manually assisted.

• Specs: 70+5 MFD (microfarad) | 370/440V dual-rated | Round case | ±3% factory tolerance | CBB65 rated
• OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances. Aftermarket units commonly run ±10% MFD drift, which accelerates compressor wear, shortens fan motor life, and can void equipment warranties.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance function. Photograph all wiring connections before disconnecting the old unit.
• Warranty: 1-year OEM factory warranty. Orders placed before 3 PM ship same business day from our warehouse.

Compatibility: Engineered for the Carrier PY4GNAA48090AA packaged unit. Note that P291-7053RS has been superseded by P291-7054R — both are fulfilled as the current OEM specification. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering. Have questions about fitment?
