OEM Carrier Run Capacitor P291-3543 for Model FA4ANF036015AEAA

This genuine Carrier P291-3543 run capacitor keeps your blower motor running smoothly inside the FA4ANF036015AEAA fan coil air handler. The capacitor provides the continuous phase-shifted voltage the PSC motor needs to start and maintain proper rotation, ensuring steady airflow and consistent cooling performance. A weak or failed run capacitor causes hard starting, motor humming, overheating, and tripped breakers, so replacing it restores full efficiency. This part is matched to the exact electrical rating specified for the FA4ANF036015AEAA, so it drops right in with no guesswork. Installation is straightforward for an experienced DIYer or HVAC tech: shut off power, discharge the old capacitor, note the terminal wiring, and swap it in within about 20 minutes using basic hand tools. Always confirm the microfarad and voltage rating before installing. We stock this OEM Carrier capacitor and ship same-day on all orders placed before 3PM CST, so your system is back up and cooling fast. Order with confidence from NationalHVACParts.com.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4ANF036015AEAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4ANF036015AEAA. 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 FA4ANF036015AEAA?
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.
