OEM Carrier Run Capacitor P291-3543 for Model FA4ANF036010AGAA

This genuine OEM Carrier P291-3543 run capacitor restores strong, steady airflow in the FA4ANF036010AGAA fan coil air handler. The run capacitor provides the continuous current the permanent split capacitor blower motor needs to start and maintain proper speed, keeping your system efficient and quiet. Telltale signs of a failing capacitor include a humming motor that won't spin, reduced airflow, motor overheating, and repeated breaker trips. Replacing it with an OEM unit rated for the FA4ANF036010AGAA solves these issues and guards the motor against damage. The job is approachable for a careful DIYer: disconnect power at the breaker, discharge the old capacitor safely, transfer the wires to the matching terminals, and clamp in the new part, usually within about 20 minutes. Always confirm the microfarad and voltage rating before reconnecting power. We ship this part same-day on all orders placed before 3PM CST, minimizing your downtime. Order genuine Carrier components from NationalHVACParts.com with confidence and fast delivery.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4ANF036010AGAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4ANF036010AGAA. 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 FA4ANF036010AGAA?
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.
