OEM Carrier Single Run Capacitor P291-1003 for Model FB4ANF030008ACAA

This is the factory-specified OEM single run capacitor (part number P291-1003) for the Carrier FB4ANF030008ACAA air handler. The run capacitor maintains a continuous phase-shifted current to keep the blower motor running at peak efficiency. When it degrades or fails, the blower motor may hum without starting, run sluggishly, overheat, or cause the air handler to trip on thermal overload — leaving your system unable to move conditioned air through the home.

  • Specs: Single run capacitor | Factory OEM-matched MFD rating | 370V or 440V rated | Cylindrical case design | Tight factory tolerance (±3% or better) for motor longevity
  • OEM vs Generic: This OEM unit is built to Carrier's exact capacitance and voltage specifications. Off-brand replacements often carry ±10% MFD tolerances, causing premature motor wear, reduced efficiency, and potential compressor or motor failure over time.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling using an insulated resistor or discharge tool. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter for verification. Photograph all wiring connections before disconnecting the old capacitor.
  • Warranty: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — get your system back up fast.

Compatibility: Designed specifically for the Carrier FB4ANF030008ACAA residential air handler. Always verify the MFD rating and voltage printed on your existing capacitor's label or the unit's data plate before ordering to ensure an exact match. Not sure? Our HVAC parts specialists are available to confirm fitment before you buy. Order today and enjoy same-day shipping on all in-stock parts.

Frequently Asked Questions

Does this Capacitor fit my Carrier FB4ANF030008ACAA?
Yes. This is the factory-specified OEM capacitor for the Carrier FB4ANF030008ACAA. 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 FB4ANF030008ACAA?
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?
