OEM Carrier Start Capacitor P281-1766 for Model CA16NA04200GBAAA

This is the genuine OEM start capacitor (part number P281-1766) for the Carrier CA16NA04200GBAAA split-system air conditioner. The start capacitor provides the extra electrical boost the compressor motor needs to overcome inertia at startup. Without a functioning start capacitor, the compressor struggles to start, draws excessive current, and may trip the breaker or hum continuously without engaging — symptoms that often indicate this part has failed or is degrading.

  • Specs: OEM-matched microfarad (MFD) rating | Factory-specified voltage rating | Engineered to Carrier's exact ±5% tolerance for reliable compressor engagement on every cycle
  • OEM vs Generic: This factory-original Carrier capacitor (P281-1766) meets the precise electrical specifications for the CA16NA04200GBAAA. Aftermarket start capacitors frequently fall outside acceptable MFD tolerance, causing repeated hard-start failures and accelerated compressor wear that can lead to costly compressor replacement.
  • Install Difficulty: 2/5 — Always disconnect power and discharge the old capacitor before handling. Tools needed: insulated screwdriver, 1/4" nut driver, needle-nose pliers, and a multimeter to verify the old capacitor has failed. Photograph all wiring connections before removal.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock and ships same business day from our warehouse so your system is back up fast.

Compatibility: Designed specifically for the Carrier CA16NA04200GBAAA split-system condenser. Always verify the MFD and voltage ratings on your unit's data plate match before installation. Not sure this is the right part? Our HVAC parts specialists can confirm fitment before you order — just reach out before placing your order and we'll get you the right part the first time.

Frequently Asked Questions

Does this Capacitor fit my Carrier CA16NA04200GBAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier CA16NA04200GBAAA. 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 CA16NA04200GBAAA?
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.
