OEM Carrier Dual Run Capacitor 45+5 MFD 370/440V for Model PY3PNA030060AA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PY3PNA030060AA air conditioning system, supplied under Carrier/Totaline part numbers P291-4553RS (original) and its current factory successor P291-4554RS. A dual run capacitor serves as the electrical energy reservoir that starts and sustains both the compressor (HERM terminal, 45 MFD) and the condenser fan motor (FAN terminal, 5 MFD) simultaneously. When this capacitor weakens or fails, you'll typically hear a low hum with no motor movement, experience short-cycling, notice warm air coming from the unit, or find the compressor attempting to start but immediately tripping on thermal overload. Also included in this kit listing are single-run capacitors P291-0403 and P291-1503 for auxiliary motor circuits on this model.

  • Specs: 45+5 MFD (microfarad) | 370/440V dual-rated | Round case, ~2" diameter | ±6% tolerance | 50/60 Hz | CBB65B rated | UL approved current interrupter | Non-PCB castor oil dielectric fluid
  • OEM vs Generic: This is a genuine Carrier/Totaline OEM capacitor built to exact factory tolerances. Generic aftermarket capacitors often carry a ±10% MFD tolerance, which accelerates compressor wear, shortens motor life, and can void system warranties.
  • Install Difficulty: 2/5 — Discharge the old capacitor fully before touching any terminals (use an insulated screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to confirm capacitance). Always photograph existing wiring before disconnecting. Label HERM, FAN, and COMMON terminals before removal.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier model PY3PNA030060AA. Cross-references include OEM part numbers P291-4553RS, P291-4554RS (current successor), P291-0403, P291-1503, and legacy cross HC98JA046. Verify the MFD rating and voltage on your unit's data plate before ordering — our fitment team is available to confirm compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 370/440V — PY3PNA030060AA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 370/440V — PY3PNA030060AA. 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 45+5 MFD 370/440V — PY3PNA030060AA?
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?
