OEM Carrier Dual Run Capacitor 70+5 MFD 440V for Model PY3GNA048115AA

This OEM dual run capacitor (part number P291-7053RS) is the factory-specified replacement for the Carrier PY3GNA048115AA split-system air conditioner. The dual run capacitor simultaneously supports both the compressor and the condenser fan motor — storing and discharging the electrical energy needed to start and sustain each motor through the full operating cycle. When this capacitor weakens or fails, the most common symptoms are a loud humming or buzzing with no compressor start, a condenser fan that spins slowly or not at all, the system short-cycling within minutes of startup, or a tripped breaker from motor overload. Left unaddressed, a failed capacitor will rapidly overheat and permanently damage the compressor — making timely replacement critical.

  • Specs: 70+5 MFD (microfarad) | 370/440V dual-rated | Round case | Factory ±3% MFD tolerance | OEM part number P291-7053RS (superseded by P291-7054R)
  • OEM vs Generic: OEM capacitors are manufactured to exact Carrier factory tolerances, ensuring proper motor starting torque and run efficiency. Generic aftermarket units often carry a ±10% MFD tolerance, which accelerates motor bearing wear and can shorten compressor life significantly over time.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals (use an insulated screwdriver across each terminal pair). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. The entire swap typically takes under 20 minutes.
  • Warranty & Shipping: 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model PY3GNA048115AA. Note that OEM part P291-7053RS has been superseded by updated part number P291-7054R — both are functionally identical at 70+5 MFD 370/440V. Always verify the MFD rating and voltage stamped on your existing capacitor's label before ordering. Our parts specialists are available to confirm fitment prior to purchase — reach out before you order if you have any questions.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 70+5 MFD 440V — PY3GNA048115AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 70+5 MFD 440V — PY3GNA048115AA. 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 70+5 MFD 440V — PY3GNA048115AA?
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?
