OEM Carrier Run Capacitor P291-3554 for Model FB4ANB048005ABAA

This OEM Carrier run capacitor (P291-3554) supports the blower motor in your FB4ANB048005ABAA fan coil air handler, delivering the steady phase-shift current the motor needs to start and run efficiently. A weak or bulging capacitor causes hard starts, humming, overheating, or a motor that won't spin at all. This genuine factory-rated dual/round capacitor is matched to the exact microfarad and voltage specification for the FB4ANB048005ABAA, ensuring proper motor torque and protecting against premature motor burnout. Direct-fit replacement connects to the original motor leads and mounting strap with no modification required. Installation is straightforward for a knowledgeable DIYer, but capacitors store a dangerous charge—always discharge it safely and shut off power at the breaker before servicing, or call a licensed technician. Using OEM Carrier parts guarantees the correct capacitance and a long service life compared to generic substitutes that drift out of spec. In stock and ships same-day on orders placed before 3PM CST, getting your air handler running quietly and reliably with minimal downtime.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FB4ANB048005ABAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FB4ANB048005ABAA. 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 run capacitor on my Carrier Model FB4ANB048005ABAA?
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 run 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 run 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?
