OEM Carrier Dual Run Capacitor 45+5 MFD 370V for Model PH10JA03600GAJAA

This OEM dual run capacitor (part# P291-4553RS) is the factory-specified replacement for the Carrier PH10JA03600GAJAA heat pump condenser. The dual run capacitor stores and releases the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. When it fails, you'll typically notice a loud hum with no motor movement, intermittent short-cycling, warm air from the system, or a condenser fan that spins only when manually nudged. Left unaddressed, a weak or failed capacitor accelerates compressor wear and can lead to costly motor burnout.

  • Specs: 45+5 MFD (microfarad) | 370V rated | Round case | ±6% tolerance | 50/60 Hz | AFC: 10,000 | Non-PCB castor oil dielectric fluid | UL approved current interrupter
  • OEM vs Generic: This is a genuine OEM-grade replacement built to Carrier factory tolerances. Generic capacitors commonly ship at ±10% MFD variance, placing unnecessary strain on compressor windings and shortening fan motor life — particularly in high-ambient heat pump applications.
  • Install difficulty: 2/5 — Always discharge the old capacitor with an insulated screwdriver before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before disconnecting. Match terminal labels (HERM, FAN, COM) exactly on reinstall.
  • Warranty: 1-year OEM replacement warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH10JA03600GAJAA heat pump condenser unit. Always verify the MFD rating and voltage printed on your unit's data plate before ordering — using an incorrect capacitor rating will void your warranty and may damage connected motors.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 370V — PH10JA03600GAJAA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 45+5 MFD 370V — PH10JA03600GAJAA. 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 — PH10JA03600GAJAA?
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?
