OEM Carrier Single Run Capacitor P291-1003 for Model FA4ANF042015ABAA

This is the factory-specified OEM single run capacitor (part number P291-1003) for the Carrier FA4ANF042015ABAA air handler. The run capacitor provides the continuous phase-shifted current required to keep the blower motor running at peak efficiency. When this component fails, the blower motor may hum without starting, run sluggishly, overheat, or shut down entirely — leaving your system unable to move conditioned air through the home. Replacing it promptly protects the motor from burnout caused by sustained low-voltage draw.

  • Specs: Single run capacitor | OEM part number P291-1003 | Factory-rated MFD and voltage matched to FA4ANF042015ABAA blower motor specifications | Round case with spade terminals
  • OEM vs Generic: This OEM capacitor is manufactured to Carrier's exact tolerance specifications (±3% MFD). Generic alternatives commonly run ±10% tolerance, which causes the blower motor to work harder, shortening its service life and risking premature failure of an expensive component.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removal to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed as a direct OEM replacement for the Carrier FA4ANF042015ABAA fan coil air handler. Always verify the MFD rating and voltage printed on your existing capacitor or the unit's data plate before ordering to confirm fitment. Not sure if this part fits your system? Our HVAC parts specialists verify fitment before you buy — contact us before placing your order.

Frequently Asked Questions

Does this Capacitor fit my Carrier FA4ANF042015ABAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FA4ANF042015ABAA. 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 FA4ANF042015ABAA?
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.
