OEM Carrier Run Capacitor P291-4554 for Model FA4ANF048010ACAA

This OEM Carrier run capacitor (P291-4554) provides the continuous phase shift that keeps your motor running efficiently on the FA4ANF048010ACAA fan coil. A worn capacitor — bulged, leaking, or reading low on microfarads — causes hard starts, humming, overheating, and premature motor failure. Replacing it is the single most cost-effective repair you can make to restore reliable operation. This genuine Carrier capacitor matches the factory microfarad and voltage rating precisely, ensuring your motor draws the correct amperage and runs cool. Constructed with high-quality dielectric film, it withstands the heat of attic and closet installations for long service life. Installation is easy and typically takes 15-20 minutes: shut off power, safely discharge the old capacitor with an insulated screwdriver, photograph the terminal connections, and transfer the leads to matching tabs. A basic nut driver is all you need. The OEM-spec part avoids the early failures common with generic capacitors. We stock this part and ship same-day on orders placed before 3PM CST. Guaranteed fit for the FA4ANF048010ACAA air handler.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4ANF048010ACAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4ANF048010ACAA. 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 FA4ANF048010ACAA?
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?
