OEM Carrier Run Capacitor P291-4554 for Model FC4BNB048008ABAA

This OEM Carrier run capacitor (P291-4554) delivers the steady electrical boost your FC4BNB048008ABAA fan coil blower motor relies on for proper torque and airflow. A failing run capacitor is one of the most common causes of a blower that hums but won't spin, starts slowly, or overheats and shuts down. This genuine Carrier part matches the original capacitance and voltage rating exactly, restoring smooth, efficient motor operation and guarding against premature burnout. Replacement is a moderate DIY repair for anyone comfortable around electrical components: turn off power at the breaker, discharge the old capacitor with an insulated screwdriver, photograph the lead positions, and install the new unit in about 20 minutes. Always confirm the printed ratings before reconnecting. Using a factory capacitor instead of a generic one preserves system efficiency and avoids repeat failures. In stock and shipping same-day when ordered before 3PM CST, so you can finish the repair today. Guaranteed fit for the FC4BNB048008ABAA fan coil.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FC4BNB048008ABAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FC4BNB048008ABAA. 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 FC4BNB048008ABAA?
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?
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.
