OEM Carrier Dual Run Capacitor 45+5 MFD 370V for Model PH3GNA030000AB

This OEM dual run capacitor (part number P291-4553RS, superseded by P291-4554RS) is the factory-specified replacement for the Carrier PH3GNA030000AB air conditioner. The dual run capacitor provides the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. When this component fails, you'll typically hear a low hum with no motor movement, notice the system short-cycling, or find the outdoor fan spinning slowly or not at all — leaving your home without cooling.

  • Specs: 45+5 MFD (microfarad) | 370V rated | Round case | ±6% tolerance | 50/60 Hz | AFC: 10,000 | Castor oil protected | No PCBs | UL approved current interrupter
  • OEM vs Generic: This OEM-spec capacitor meets exact factory tolerance requirements. Generic capacitors commonly run at ±10% MFD deviation, which accelerates wear on both the compressor and condenser fan motor, potentially voiding equipment warranties.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting the old unit. Follow all local electrical codes and shut off power at the disconnect box before beginning work.
  • Warranty: 1-year manufacturer warranty. Orders ship same business day from our warehouse when placed before 3 PM local time.

Compatibility: Fits Carrier model PH3GNA030000AB. Note: P291-4553RS has been superseded by P291-4554RS — both carry identical 45+5 MFD 370V specifications. Always verify MFD and voltage ratings on your unit's data plate before ordering. Need fitment confirmation?

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 370V — PH3GNA030000AB?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 370V — PH3GNA030000AB. 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 370V — PH3GNA030000AB?
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?
