OEM Carrier Run Capacitor P291 Dual for Model FA4ANF048000AAAA

This genuine OEM Carrier run capacitor supplies the steady phase-shifted current that keeps the blower motor in your Carrier FA4ANF048000AAAA fan coil running efficiently and quietly. A worn or failed capacitor is one of the most frequent HVAC failures, commonly causing a motor that hums without starting, overheating, reduced airflow, or nuisance overload trips. A correctly rated new capacitor restores full starting torque and smooth performance. Built to the exact microfarad and voltage specification of the factory part, it matches the FA4ANF048000AAAA precisely and lasts far longer than generic alternatives prone to early failure. Installation is simple for a qualified technician: shut off power at the disconnect, discharge the old capacitor, record the terminal wiring, and transfer the leads to the matching tabs. Most swaps take just 15-20 minutes. Verify the ratings against your existing capacitor before installing. In stock and ships same-day on orders placed before 3PM CST, restoring your air handler's airflow without delay. Contact our parts team anytime for fit assistance.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4ANF048000AAAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4ANF048000AAAA. 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 FA4ANF048000AAAA?
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?
