OEM Carrier Run Capacitor P291-4554 for Model FA4CNC048010AAAA

This OEM Carrier run capacitor (P291-4554-style) delivers the steady phase shift your FA4CNC048010AAAA fan coil's blower motor needs to start and run efficiently. A worn capacitor — bulging, leaking, or off-rating — causes humming, hard starts, overheating, or a motor that won't spin. Built to Carrier's exact microfarad and voltage specs, it restores proper torque and shields the blower from early burnout. This direct-fit replacement matches the original mounting and terminal configuration on the FA4CNC048010AAAA. Installation is easy and typically takes 15-20 minutes: discharge the old capacitor safely, note the wire positions, and transfer the leads. Always cut power at the disconnect first, since capacitors store a charge. Genuine OEM parts ensure correct ratings and longer life than generic substitutes. This capacitor is in stock and ships same-day on orders before 3PM CST, so you can restore cooling fast. Reach out to our HVAC parts team if you need help verifying the right capacitor for your system.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FA4CNC048010AAAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FA4CNC048010AAAA. 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 FA4CNC048010AAAA?
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?
