OEM Carrier Run Capacitor P291-3543 for Model FB4ANF024000AEAA

This genuine OEM Carrier run capacitor (part P291-3543) provides the steady phase shift that keeps the blower motor in your Carrier FB4ANF024000AEAA fan coil running smoothly and efficiently. A weak or bulged capacitor is one of the most common HVAC failures, causing a motor that hums but will not start, overheats, or short-cycles. Replacing it with the factory-rated microfarad and voltage value restores full motor torque and prevents premature motor burnout. Manufactured to Carrier's exact specifications, this capacitor matches the original mounting and terminal configuration for a true plug-in fit. Installation is an easy DIY repair: shut off power, discharge the old capacitor safely, photograph the wiring, transfer the leads, and secure the new unit. Most repairs take 15 to 20 minutes. Choosing the correct OEM run capacitor avoids the wrong-rating guesswork that aftermarket parts invite. We stock this part and ship same-day on orders placed before 3PM CST so you can get the air moving again fast. Order today for an authentic Carrier replacement matched to your model.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FB4ANF024000AEAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FB4ANF024000AEAA. 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 FB4ANF024000AEAA?
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?
