OEM Carrier Start Capacitor P281-1766 for Model PH15NA01800GBAAA

This is the factory OEM start capacitor for the Carrier PH15NA01800GBAAA packaged heat pump unit. The start capacitor provides the high-torque electrical boost the compressor motor needs during startup. Without a functioning start capacitor, the compressor will struggle to start, draw excessive amperage, hum without engaging, or trip the breaker repeatedly — all signs of a failed or weak capacitor that needs immediate replacement.

  • Specs: OEM Part Number P281-1766 | Factory-matched capacitance and voltage rating | Engineered to exact Carrier tolerances for the PH15NA01800GBAAA platform
  • OEM vs Generic: This is a genuine OEM Carrier capacitor — not an aftermarket substitute. OEM units deliver factory-spec capacitance tolerance (±5% or better), reducing compressor wear and extending equipment life versus generic alternatives that often drift ±10% or more out of the box.
  • Install Difficulty: 2/5 — Always disconnect power and discharge any residual voltage from the old capacitor before handling. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty coverage. Orders placed before cutoff ship the same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement for Carrier model PH15NA01800GBAAA. Always verify the capacitance (MFD) and voltage ratings on your unit's data plate match this part before ordering. Our technical team is available to confirm fitment — reach out before you buy if you have any questions.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH15NA01800GBAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier PH15NA01800GBAAA. 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 PH15NA01800GBAAA?
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.
