OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PY4GNAB24060NA

This is the OEM factory-specified dual run capacitor for the Carrier PY4GNAB24060NA condensing unit, sold under Carrier part number P291-4054RS. The dual run capacitor stores and releases the precise electrical charge required to start and sustain both the compressor and the condenser fan motor simultaneously. When this capacitor weakens or fails, common symptoms include a loud humming noise with no motor movement, the outdoor unit failing to start at all, the compressor starting but the fan not spinning, or the system short-cycling and tripping on high pressure. Left unaddressed, a failed capacitor can overstress and permanently damage the compressor — making prompt replacement critical.

• Specs: 40+5 MFD (microfarad) | 440V rated | Round case | ±6% tolerance | 50/60 Hz | Castor oil protected | No PCB | UL recognized
• OEM vs Generic: This is a genuine Carrier OEM part (P291-4054RS) built to exact factory tolerances. Generic capacitors commonly run ±10% MFD deviation, accelerating motor wear and shortening compressor life — OEM spec ensures reliable start torque every cycle.
• Install Difficulty: 2/5 — Always discharge the capacitor fully before touching terminals (use a 20kΩ resistor or insulated screwdriver). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Swap terminals one at a time to avoid miswiring.
• Warranty: 1-year OEM manufacturer's warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY4GNAB24060NA condensing unit. Also replaces legacy Carrier part numbers HC98KA041 and P291-4053RS. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering — do not substitute a different MFD value without consulting an HVAC technician. Our parts team is available to verify fitment before you complete your purchase.
