OEM Carrier Dual Run Capacitor P291-7054R for Model PY4GNAB48115AN

This OEM dual run capacitor (part number P291-7054R) is the factory-specified replacement for the Carrier PY4GNAB48115AN packaged gas-electric unit. The dual run capacitor simultaneously supports two motors — the compressor and the condenser fan motor — storing and releasing the precise electrical charge needed to start and sustain both components throughout every cooling cycle. When this capacitor begins to fail, common symptoms include a loud humming noise with no motor startup, the condenser fan spinning slowly or not at all, the system tripping on high-pressure lockout, or the unit short-cycling within minutes of startup. Left unaddressed, a weak or failed capacitor can cause compressor damage, significantly increasing repair costs.

  • Part Specs: OEM part number P291-7054R | Dual run (compressor + fan) | Factory-matched MFD and voltage rating | Round capacitor case | ±3% tolerance for precise motor performance
  • OEM vs. Generic: This is a genuine OEM capacitor engineered to Carrier's exact factory specification. Generic aftermarket capacitors commonly carry ±10% MFD tolerance, which accelerates wear on both the compressor and condenser fan motor and can void equipment warranties.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Confirm MFD and voltage ratings match your unit's data plate prior to installation.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY4GNAB48115AN 4-ton packaged gas-electric unit. Always verify the MFD and voltage rating on your existing capacitor and your unit's data plate before ordering to ensure a correct fit. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY4GNAB48115AN?
Yes. This is the factory-specified OEM capacitor for the Carrier PY4GNAB48115AN. 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 PY4GNAB48115AN?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
