OEM Carrier Run Capacitor P291-3554R for Model FD3ANA018000AAAA

Get your Carrier FD3ANA018000AAAA back to peak efficiency with this genuine OEM run capacitor (P291-3554R). The run capacitor maintains the continuous phase shift that keeps your blower motor turning smoothly after it starts, ensuring proper torque and energy-efficient operation. A failing capacitor reveals itself through humming motors, hard or failed starts, intermittent cycling, overheating, and climbing utility bills — and a bad capacitor can quickly destroy the motor it serves. This part is built to Carrier's exact microfarad and voltage ratings, guaranteeing correct output and long service life without the risk of mismatched universal parts. It drops into the FD3ANA018000AAAA using the original mounting strap and terminal arrangement for a fast, no-modification install. Difficulty is moderate: because capacitors store an electrical charge, always cut power and discharge the old unit before handling. A capable DIYer can finish in 20–30 minutes with insulated tools, but a licensed technician is recommended if you're unsure. Order before 3PM CST and your capacitor ships the same business day, fast and reliable.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model FD3ANA018000AAAA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model FD3ANA018000AAAA. 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 FD3ANA018000AAAA?
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?
