OEM Carrier Run Capacitor P291-3543 for Model FB4ANB048010AEAA

This OEM Carrier run capacitor keeps the blower or condenser fan motor running at peak efficiency in your FB4ANB048010AEAA fan coil unit. A failing run capacitor causes hard starts, motor humming, or a unit that won't move air — replacing it restores proper torque and amperage to the motor windings. This dual-rated, factory-spec capacitor is engineered precisely for the FB4ANB048010AEAA, so you avoid the guesswork of generic substitutes that can shorten motor life. Installation is a moderate DIY job: shut off power at the breaker, discharge the old capacitor, photograph the wiring, and swap terminals one at a time. Most homeowners complete it in under 30 minutes with a screwdriver and nut driver. Always verify microfarad (MFD) and voltage ratings against your existing part before installing. Backed by Carrier OEM quality for reliable, long-lasting performance. In stock and ships same-day when you order before 3 PM CST, so you can get your system cooling again fast. Questions on fitment?

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FB4ANB048010AEAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FB4ANB048010AEAA. 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 FB4ANB048010AEAA?
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?
