OEM Carrier Single Run Capacitor P291-1003 for Model FA4ANC036008AAAA

This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier FA4ANC036008AAAA fan coil air handler. The run capacitor maintains a continuous phase-shifted electrical charge to keep the blower motor running at peak efficiency. When this component fails, you'll typically notice the blower motor humming but not spinning, the system short-cycling, or the air handler failing to move conditioned air altogether — even while the compressor runs normally at the outdoor unit.

  • Specs: Single run capacitor | Factory-matched MFD rating | 370V/440V rated | Cylindrical case design | ±5% OEM tolerance for precise motor performance
  • OEM vs Generic: This is a genuine OEM Carrier capacitor built to exact factory specifications. Generic capacitors often carry a wider ±10% MFD tolerance, which can cause motor overheating, reduced efficiency, and shortened blower motor life — costing far more in the long run.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, and a multimeter to verify discharge. Photograph all wiring connections before removing the old capacitor to ensure correct reinstallation.
  • Warranty: Backed by a 1-year OEM factory warranty. Orders placed before cutoff ship the same business day from our climate-controlled parts warehouse.

Compatibility: Designed specifically for the Carrier FA4ANC036008AAAA 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 an exact match. Not sure?

Frequently Asked Questions

Does this Capacitor fit my Carrier FA4ANC036008AAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FA4ANC036008AAAA. 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 FA4ANC036008AAAA?
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.
