OEM Carrier Dual Run & Start Capacitor Kit — P291-3554RS + P281-8806 for Model PH10JA036000AGAA

This factory-matched OEM capacitor kit contains both the dual run capacitor (P291-3554RS) and the start capacitor (P281-8806) required for the Carrier PH10JA036000AGAA heat pump system. The dual run capacitor continuously powers both the compressor and the condenser fan motor, while the start capacitor delivers the high-torque surge needed to kick the compressor into motion on each cycle. When either capacitor fails, you'll experience symptoms ranging from an audible hum with no motor movement, a system that trips the breaker, or a unit that starts briefly and then shuts down within seconds. Replacing both together is the industry-recommended approach — if one has failed, the other is under equal stress and near end of life.

  • Dual Run Capacitor (P291-3554RS) Specs: 35+5 MFD (microfarad) | 440V rated | Round case | ±6% tolerance | Non-PCB dielectric fluid | UL-approved pressure-sensitive current interrupter
  • Start Capacitor (P281-8806) Specs: 88–108 MFD | 330V rated | Round case | Includes bleed resistor | Factory-spec direct drop-in replacement
  • OEM vs Generic: OEM Carrier/Totaline capacitors are held to tighter manufacturing tolerances than aftermarket alternatives. Generic units often deviate ±10% MFD from rating, increasing thermal stress on compressor windings and shortening equipment life. This kit is genuine factory-authorized.
  • Install difficulty: 2/5 — Always discharge the capacitor before handling — it retains lethal voltage after shutdown. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. The start capacitor bleed resistor must be reinstalled on the new unit. If in doubt, call a licensed HVAC technician.
  • Warranty: 1-year OEM factory warranty on both capacitors. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as the exact OEM replacement kit for Carrier model PH10JA036000AGAA. Verify your unit's data plate MFD and voltage ratings before ordering. Our fitment team is available to confirm compatibility — reach out before you buy for total peace of mind. In stock and ships today.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH10JA036000AGAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH10JA036000AGAA. 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 PH10JA036000AGAA?
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.
