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.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 40+5 MFD 440V — PY4GNAB24060NA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 40+5 MFD 440V — PY4GNAB24060NA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the capacitor on my Carrier OEM Carrier Dual Run Capacitor 40+5 MFD 440V — PY4GNAB24060NA?
Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.
My AC hums but won’t start. What part do I need?
An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).
Is this capacitor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier capacitor?
OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.
How fast does National HVAC Parts ship?
