OEM Carrier Dual Run Capacitor 40+5 MFD 370V for Model PH1PNA036000AABA

This OEM dual run capacitor (part number P291-4053, superseded by P291-4054RS) is the factory-specified replacement for the Carrier PH1PNA036000AABA packaged heat pump unit. The dual run capacitor stores and releases the electrical charge needed to start and sustain both the compressor and condenser fan motor simultaneously. A failing capacitor is one of the most common causes of HVAC system failure — symptoms include an audible hum with no motor movement, a compressor that kicks on but immediately shuts off, or a condenser fan that spins slowly or not at all. Also included is the companion single run capacitor P291-1503 (15 MFD 370V oval), which independently supports the blower or auxiliary motor circuit on this unit.

  • Primary Capacitor Specs (P291-4053 / P291-4054RS): 40+5 MFD (microfarad) | 370V rated | Oval case | ±6% tolerance | 50/60 Hz | 10,000 AFC | Castor oil protected dielectric
  • Secondary Capacitor Specs (P291-1503): 15 MFD | 370V | Oval case | Single run | Non-PCB dielectric fluid | UL-approved current interrupter | Multiple electrical terminals
  • OEM vs Generic: OEM Carrier capacitors are manufactured to exact factory tolerances (±6% MFD). Generic aftermarket units commonly run ±10% or worse, accelerating compressor and motor wear and shortening system lifespan. OEM is always the right choice for warranty-sensitive or commercial installations.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling — stored charge can cause serious injury. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting. Note: P291-4053 is superseded by P291-4054RS (440V round); verify your unit's data plate before ordering.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PH1PNA036000AABA packaged heat pump (3-ton, R-410A). OEM part numbers P291-4053 (dual run, 40+5 MFD 370V oval) and P291-1503 (single run, 15 MFD 370V oval). Always verify MFD rating and voltage on your unit's data plate before ordering. Our team is available to confirm fitment — call or chat before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH1PNA036000AABA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH1PNA036000AABA. 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 PH1PNA036000AABA?
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.
