OEM Carrier Start Capacitor P281-1766 for Model PH15NA036000BAAA

This is the factory-specified OEM start capacitor for the Carrier PH15NA036000BAAA heat pump system. The start capacitor provides the high-torque electrical boost the compressor motor needs during startup. Without a properly functioning start capacitor, the compressor struggles to start, draws excessive amperage, trips the breaker, or fails to start entirely — symptoms that often mimic a failed compressor. Replacing a faulty start capacitor is one of the most cost-effective repairs in HVAC service.

  • Specs: OEM Carrier start capacitor | Part number P281-1766 | Factory-matched microfarad (MFD) and voltage rating | Engineered to exact factory tolerances for the PH15NA036000BAAA platform
  • OEM vs Generic: This OEM unit is manufactured to Carrier's precise MFD tolerance (±3%). Aftermarket start capacitors frequently fall outside spec, leading to hard-starts, compressor overheating, and shortened equipment life — making the OEM choice the smart long-term investment.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling. Tools required: 1/4" nut driver, needle-nose pliers, and a multimeter for verification. Photograph all wiring connections prior to removal. If unsure, consult a licensed HVAC technician.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed and tested for the Carrier PH15NA036000BAAA (3-ton, single-stage heat pump). Always verify the MFD and voltage ratings on your unit's data plate before ordering to ensure an exact match. Our technical team is available to confirm fitment — don't hesitate to reach out before you buy.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH15NA036000BAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH15NA036000BAAA. 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 PH15NA036000BAAA?
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.
