OEM Carrier Run Capacitor P291-3554RS for Model FA4BNC036008AAAA

This OEM Carrier run capacitor (P291-3554RS) supplies the steady phase-shifting voltage that keeps the blower motor in your FA4BNC036008AAAA fan coil unit starting smoothly and running efficiently. Over time capacitors weaken and fail, leading to motor humming, hard starts, overheating, reduced airflow, and eventual motor burnout, so timely replacement protects your system and restores performance. Made to exact factory microfarad and voltage ratings, this capacitor is a direct drop-in replacement that fits and wires exactly like the original for trouble-free operation. Installation is a moderate DIY job for anyone comfortable around electrical components: cut power at the breaker, safely discharge the old capacitor, note the terminal connections, and install the new one in minutes with basic tools. If you'd rather not handle electrical parts, a licensed HVAC technician can swap it quickly. Genuine OEM sourcing and our quality guarantee mean dependable, quiet cooling. In stock and ships same-day on orders before 3PM CST, so your Carrier air handler is back to full airflow fast.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4BNC036008AAAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4BNC036008AAAA. 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 FA4BNC036008AAAA?
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?
