OEM Carrier Run Capacitor P291-3543 for Model FC4BNF036008AAAA

This genuine OEM Carrier run capacitor is the exact factory replacement for the FC4BNF036008AAAA fan coil. It provides the steady, phase-shifted current the blower motor relies on to start cleanly and hold consistent speed, keeping airflow strong and energy use in check. A failing capacitor commonly shows up as a motor that hums but won't turn, intermittent blower operation, tripped breakers, or premature motor wear. Manufactured to Carrier's precise microfarad and voltage rating for the FC4BNF036008AAAA, this part delivers a guaranteed electrical match that protects your motor and preserves system performance — something universal parts often can't promise. A qualified technician can typically finish the replacement in 20 to 30 minutes with basic tools, after shutting off power at the breaker and discharging the old capacitor for safety. It's a manageable repair for those comfortable with HVAC electrical work. Order before 3PM CST and your in-stock capacitor ships the same business day, getting your comfort system running smoothly again as quickly as possible.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FC4BNF036008AAAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FC4BNF036008AAAA. 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 FC4BNF036008AAAA?
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.
