OEM Carrier Dual Run Capacitor 35+5 MFD 440V for Model PH1ZNA030000AAAA

This is the factory-specified OEM dual run capacitor (part number P291-3554RS) for the Carrier PH1ZNA030000AAAA heat pump system. A dual run capacitor stores and delivers the electrical charge required to start and continuously run both the compressor and the condenser fan motor from a single round can. When this capacitor fails, you'll typically experience a loud hum with no motor movement, the unit short-cycling within seconds of startup, or the condenser fan spinning weakly or not at all — all signs of imminent compressor damage if left unaddressed. A second OEM part number for this unit, P291-1503, covers the single run capacitor variant; confirm your existing capacitor's MFD ratings before ordering.

  • Specs: 35+5 MFD (microfarad) | 440V rated | Round case | ±6% tolerance | 50/60 Hz | 10,000 AFC | Castor oil protected | No PCBs | UL approved
  • OEM vs Generic: This is a genuine Carrier OEM capacitor meeting exact factory specifications. Generic capacitors often carry a ±10% MFD tolerance versus the OEM ±6%, leading to accelerated motor and compressor wear over time.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before touching any terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Replace like-for-like on MFD ratings and voltage.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our NationalHVACParts.com warehouse. Free shipping on orders over $99.

Compatibility: Designed for the Carrier PH1ZNA030000AAAA heat pump system. Replaces legacy Carrier part numbers HC98JA036D, HC98CA035, HC98CA036, and 319186-701. Always verify your unit's data plate MFD and voltage ratings before ordering. Our team is available to confirm fitment — contact us before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 35+5 MFD 440V — PH1ZNA030000AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 35+5 MFD 440V — PH1ZNA030000AAAA. 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 35+5 MFD 440V — PH1ZNA030000AAAA?
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?
