OEM Carrier Dual Run Capacitor 40+5 MFD 440V for Model PY4GNAB30060AA

This is the OEM factory-specified dual run capacitor for the Carrier PY4GNAB30060AA condensing unit, sold under Carrier part number P291-4054RS. The dual run capacitor stores and releases the precise electrical charge needed to start and sustain both the compressor and the condenser fan motor during every cooling cycle. When this component degrades or fails, you'll typically notice one or more of the following: a loud humming sound with no motor movement, the condenser fan spinning weakly or not at all, the compressor short-cycling, or the system tripping on high-pressure lockout within minutes of startup. Left unaddressed, a weak capacitor accelerates wear on the compressor — the most expensive component in your system.

  • Specs: 40+5 MFD (microfarad) | 440V rated | Round case | 50/60 Hz | ±6% tolerance | AFC: 10,000 | Castor oil protected, No PCB | Height: 5 5/16" | Diameter: 1 15/16"
  • OEM vs Generic: This OEM Carrier capacitor is manufactured to exact factory tolerances. Generic aftermarket capacitors frequently run at ±10% MFD variance, placing additional strain on the compressor windings and condenser fan motor — potentially voiding equipment warranties and shortening system lifespan.
  • Install Difficulty: 2/5 — A straightforward DIY repair for anyone comfortable with basic electrical safety. Always shut off power at the disconnect and breaker first, then discharge the capacitor terminals using an insulated resistor before touching any wires. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting.
  • Warranty: 1-year OEM manufacturer warranty against defects. Orders placed before our daily cutoff ship the same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Carrier model PY4GNAB30060AA. Also replaces legacy Carrier part numbers HC98KA041 and P291-4053RS. Always confirm the MFD rating and voltage printed on your existing capacitor's label before ordering to ensure a proper match. Have questions about fitment?

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 40+5 MFD 440V — PY4GNAB30060AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 40+5 MFD 440V — PY4GNAB30060AA. 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 — PY4GNAB30060AA?
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?
