OEM Carrier Dual Run Capacitor & Start Capacitor Kit for Model PH10JA042000AHAA

This factory-matched OEM capacitor kit includes both the dual run capacitor (P291-4054RS) and the start capacitor (P281-8806) — the exact components specified for the Carrier PH10JA042000AHAA packaged heat pump unit. The dual run capacitor continuously supplies the electrical charge needed to keep the compressor and condenser fan motor running, while the start capacitor delivers the high-torque burst required to cycle the compressor on under load. When either component fails, symptoms include a distinct humming with no motor movement, a compressor that trips on thermal overload, or a system that short-cycles within the first few minutes of operation. Replacing both together is best practice — if one has failed, the other is under increased stress.

  • Dual Run Capacitor Specs (P291-4054RS): 40+5 MFD | 440V rated | Round case | ±6% tolerance | 50/60 Hz | AFC 10,000 | Castor Oil protected | No PCB
  • Start Capacitor Specs (P281-8806): 88–108 MFD | 330V rated | Oval case | 2.06" diameter | With bleed resistor | 50/60 Hz
  • OEM vs Generic: These are genuine Carrier/Totaline factory-authorized parts, manufactured to exact OEM tolerances. Generic capacitors often carry ±10% MFD ratings, which accelerates motor wear, shortens compressor life, and can void equipment warranties. Always match the data plate specs exactly.
  • Install Difficulty: 2/5 — Always discharge capacitors fully before handling — stored charge is dangerous. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance setting). Photograph all wiring before disconnecting. If unsure, consult a licensed HVAC technician.
  • Warranty: 1-year OEM manufacturer warranty. In-stock orders ship same business day from our warehouse.

Compatibility: Engineered as direct OEM replacements for the Carrier PH10JA042000AHAA packaged heat pump. Verify MFD, voltage, and physical dimensions against your unit's data plate before installing. Our fitment team is available to confirm compatibility before you order — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run + Start Capacitor Kit 40+5 MFD 440V — PH10JA04200?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run + Start Capacitor Kit 40+5 MFD 440V — PH10JA04200. 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 + Start Capacitor Kit 40+5 MFD 440V — PH10JA04200?
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?
