OEM Carrier Dual Run Capacitor 45+5 MFD 370V for Model PH10JA03600GAFAA

This OEM dual run capacitor (Part# P291-4553RS) is the factory-specified replacement for the Carrier PH10JA03600GAFAA air conditioning system. The dual run capacitor stores and releases the electrical charge required to start and keep both the compressor and condenser fan motor running during every cooling cycle. When this component begins to fail, you'll typically notice the system humming without the compressor or fan spinning up, the unit short-cycling, or a complete failure to cool — all classic signs of capacitor degradation caused by heat stress and normal electrical wear over time.

  • Specs: 45+5 MFD (microfarad) | 370V rated | Round case | ±6% tolerance | 50/60 Hz | AFC: 10,000 | Non-PCB castor oil protected dielectric fluid | UL approved current interrupter | Height: 4 5/16" (4 7/8" w/ terminals) | Diameter: 2"
  • OEM vs Generic: This OEM Carrier/Totaline capacitor is manufactured to exact factory specifications, ensuring proper MFD tolerance and voltage rating for your unit. Generic aftermarket capacitors often operate at ±10% MFD tolerance, which accelerates wear on the compressor and fan motor and can void equipment warranties.
  • Install Difficulty: 2/5 — A straightforward DIY repair for most homeowners. Always shut off power at the disconnect box and discharge the old capacitor before touching any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back up fast.

Compatibility: Directly fits Carrier model PH10JA03600GAFAA. Note that P291-4553RS has been superseded by OEM part P291-4554RS — both are fully compatible direct replacements. Always verify MFD rating and voltage on your unit's data plate before ordering. Have questions about fitment? Our HVAC parts specialists verify compatibility before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 370V — PH10JA03600GAFAA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 370V — PH10JA03600GAFAA. 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 — PH10JA03600GAFAA?
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?
