OEM Carrier Run Capacitor P291-3543 for Model FA4ANF036000AGAA

This OEM Carrier run capacitor (part P291-3543) is the genuine dual-rated capacitor matched to the FA4ANF036000AGAA fan coil. The run capacitor delivers the steady phase-shifted current the blower motor relies on to start and hold the proper speed, keeping airflow consistent across the indoor coil. When the capacitor weakens you'll notice hard starts, reduced airflow, a humming or stalled motor, or short-cycling. Since this part is built to Carrier's exact microfarad and voltage specs for the FA4ANF036000AGAA, you avoid the motor strain and guesswork that come with universal capacitors. Replacement is fast for a trained HVAC technician, typically 15-30 minutes: kill power at the disconnect, discharge the old capacitor safely, record the wiring, and install the new one. Orders placed before 3PM CST ship same-day from our warehouse to keep your repair on schedule. Restore strong, reliable blower operation and protect the motor with the correct OEM capacitor instead of a generic guess. Backed by genuine Carrier quality and quick shipping.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4ANF036000AGAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4ANF036000AGAA. 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 FA4ANF036000AGAA?
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?
