OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PY1PJB048115ABAA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY1PJB048115ABAA packaged unit. The dual run capacitor stores and releases the electrical charge required to start and sustain both the compressor and the condenser fan motor simultaneously. When this component degrades or fails, you'll typically hear a low hum with no motor movement, experience warm air output, or notice the system short-cycling — all classic signs of capacitor failure. This listing also includes the companion single run capacitors P291-0403 (4 MFD 370V) and P291-1503 (15 MFD) for complete capacitor servicing of this unit.

• Specs — Primary (P291-4054): 40+5 MFD (microfarad) | 370–440V dual-rated | Round case | 60 Hz | Factory-matched ±5% tolerance
• OEM vs Generic: OEM Carrier/Totaline capacitors are manufactured to exact factory tolerances, ensuring proper start torque and run efficiency. Generic capacitors commonly ship at ±10% MFD variance, which accelerates motor winding wear and shortens compressor life over time.
• Install difficulty: 2/5 — Always disconnect power at the disconnect box before opening the unit. Discharge the capacitor using an insulated screwdriver across the terminals before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wire connections before removal.
• Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for Carrier model PY1PJB048115ABAA. Always verify the MFD rating, voltage, and terminal configuration on your unit's data plate before ordering. Our team is available to confirm fitment — reach out before you buy if you have any questions.
