OEM Carrier Run Capacitor P291-4554 for Model FA4ANF048010ABAA

This OEM Carrier run capacitor (P291-4554) supplies the steady phase shift that keeps your blower or condenser motor running efficiently on the FA4ANF048010ABAA fan coil. A failing capacitor that's bulged, leaking, or out of spec produces hard starts, motor humming, overheating, and eventual burnout — which is why replacing it is the most cost-effective HVAC repair available. This genuine Carrier capacitor matches the factory microfarad and voltage rating exactly, so your motor draws correct amperage and stays cool under load. Its high-grade dielectric film construction holds up to the heat of attics and equipment closets for years of service. Installation is easy and usually takes 15-20 minutes: disconnect power, safely discharge the old capacitor with an insulated screwdriver, photograph the terminal layout, and transfer the leads to matching tabs. Only a nut driver is required. The OEM-spec part avoids the premature failures common with cheap generics. We keep this part in stock and ship same-day on orders placed before 3PM CST. Guaranteed fit for the FA4ANF048010ABAA air handler.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4ANF048010ABAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4ANF048010ABAA. 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 FA4ANF048010ABAA?
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?
