OEM Carrier Run Capacitor P291-5054 for Model FB4ASX024000AEAA

This genuine OEM Carrier run capacitor (P291-5054) supplies the continuous phase shift that keeps your FB4ASX024000AEAA fan coil blower motor running at the correct speed and torque. When a capacitor degrades, common symptoms include diminished airflow, a motor that buzzes but won't spin up, and repeated overload shutdowns. This part matches the original microfarad and voltage rating for the FB4ASX024000AEAA, providing an exact, reliable replacement. Installing a run capacitor is a great entry-level repair for a confident DIYer: turn off power at the breaker, discharge the old capacitor safely across its terminals, take a photo of the wiring, and move each lead to the matching terminal on the new capacitor, generally in 15-20 minutes. Be sure to confirm the capacitance value on your existing capacitor or unit data plate before buying. Bring back strong, quiet airflow and extend motor life with a component built to OEM standard. In stock and ships same-day when you order before 3PM CST.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FB4ASX024000AEAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FB4ASX024000AEAA. 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 FB4ASX024000AEAA?
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?
