OEM Carrier Run Capacitor P291-3543 for Model FA4ANF036015AAAA

Keep cool air flowing with this genuine OEM Carrier P291-3543 run capacitor built for the FA4ANF036015AAAA fan coil air handler. The run capacitor delivers the continuous phase-shifted current the PSC blower motor needs to start quickly and run at full speed, maintaining steady airflow and efficient operation. A worn capacitor shows up as motor humming, slow or failed starts, weak airflow, overheating, and nuisance breaker trips. Swapping in a fresh OEM unit matched to the FA4ANF036015AAAA restores performance and extends motor life. This is a beginner-friendly repair for the mechanically inclined: turn off power, discharge the old capacitor with an insulated resistor, transfer the wire leads to the identical terminals, and mount the replacement, all in roughly 20 minutes. Double-check the microfarad and voltage rating before powering up. Orders placed before 3PM CST ship the same business day so you're not left waiting in the heat. Count on NationalHVACParts.com for authentic Carrier parts and quick, reliable fulfillment.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4ANF036015AAAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4ANF036015AAAA. 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 FA4ANF036015AAAA?
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?
