OEM Carrier Dual Run Capacitor 45+5 MFD 440V for Model PY1RJA036074ABWA

This is the genuine OEM Carrier dual run capacitor (part number P291-4554RS) factory-specified for the Carrier PY1RJA036074ABWA packaged unit. The dual run capacitor simultaneously powers both the compressor and the condenser fan motor, storing and releasing the electrical charge needed to start and sustain each motor through every cooling cycle. When this capacitor fails, you'll typically notice the system humming without starting, the compressor or fan motor running intermittently, or the unit tripping on thermal overload and short-cycling within minutes. Related OEM part numbers for this system include HC30GB230 (draft inducer motor w/ capacitor), P291-0403, and P291-1003 (single run capacitors).

  • Specs: 45+5 MFD (microfarad) | 440V rated | Round case | 50/60 Hz | ±6% tolerance | AFC 10,000 | Castor Oil Protected | No-PCB | Dimensions: 3 15/16" can height, 2 7/16" diameter
  • OEM vs Generic: This is a genuine Carrier OEM capacitor built to exact factory tolerance (±6%). Off-brand generics often run ±10% MFD deviation, which accelerates compressor wear, shortens motor life, and can void equipment warranties.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals — stored charge can cause serious injury. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode). Photograph all terminal wiring before disconnecting. Confirm MFD and voltage ratings on your unit data plate before installation.
  • Warranty: 1-year OEM manufacturer warranty against defects. Orders placed before our daily cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier PY1RJA036074ABWA packaged unit. Also replaces legacy Carrier capacitor part numbers HC98KA046 and 319186-702. Always verify the MFD rating and voltage on your unit's data plate before ordering. Not sure it fits? Our HVAC parts specialists verify fitment before you order — reach out and we'll confirm compatibility fast.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 440V — PY1RJA036074ABWA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 440V — PY1RJA036074ABWA. 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 440V — PY1RJA036074ABWA?
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?
