OEM Carrier Dual Run Capacitor 35+5 MFD & Single Run Capacitor 15 MFD 370V for Model PH1PNA030000ABBA

This listing covers the two factory-specified OEM capacitors for the Carrier PH1PNA030000ABBA package heat pump unit: the P291-3553 Dual Run Capacitor (35+5 MFD, 370V) and the P291-1503 Single Run Capacitor (15 MFD, 370V). The dual run capacitor stores and delivers the electrical charge needed to start and sustain both the compressor and the condenser fan motor simultaneously. The single run capacitor supports an additional motor circuit. When either fails, you may notice humming with no motor start, the unit short-cycling within minutes, or a complete loss of cooling or heating — classic signs of capacitor failure in packaged HVAC systems.

  • Dual Run Capacitor (P291-3553) Specs: 35+5 MFD (microfarad) | 370V rated | Oval case | Terminals: HERM – C – FAN | Factory ±3% tolerance | RoHS Compliant | UL Approved
  • Single Run Capacitor (P291-1503) Specs: 15 MFD | 370V rated | Oval case | Non-PCB dielectric fluid | UL Approved current interrupter | Multiple electrical terminals
  • OEM vs Generic: These are Carrier/Totaline factory-authorized OEM capacitors, precision-matched to the PH1PNA030000ABBA's electrical specifications. Generic capacitors often carry ±10% MFD tolerance, which accelerates compressor and motor wear and can void equipment warranties. OEM units are 100% electrically tested before leaving the factory.
  • Install difficulty: 2/5 — Always discharge the capacitor fully before touching terminals — a charged capacitor can deliver a dangerous shock. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter (to verify discharge and confirm MFD before install). Photograph all wire connections before removal. Replace like-for-like: match MFD rating exactly and use same or higher voltage rating.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: These capacitors are the OEM-specified replacements for the Carrier PH1PNA030000ABBA packaged heat pump unit. Always verify the MFD and voltage ratings against your unit's data plate before ordering. Note that P291-3553 has been superseded by P291-3554, and P291-1503 has been superseded by P291-1504 — both successors carry identical electrical specifications and are fully interchangeable.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual & Single Run Capacitor Kit 35/5 MFD 370V — PH1PNA0300?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual & Single Run Capacitor Kit 35/5 MFD 370V — PH1PNA0300. 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 & Single Run Capacitor Kit 35/5 MFD 370V — PH1PNA0300?
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?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
