OEM Carrier Run Capacitor P291-4555 for Model N6D48NG480100

This OEM Carrier P291-4555 run capacitor provides the steady phase-shifted current that keeps the motor in your Carrier N6D48NG480100 running smoothly, efficiently, and at proper torque. A failing capacitor — one that is bulging, leaking, or out of spec — leads to hard starts, motor humming, overheating, breaker trips, and premature motor burnout, so timely replacement protects a far more expensive motor. This genuine OEM capacitor is built to the exact microfarad and voltage rating the N6D48NG480100 requires, ensuring correct amp draw and dependable, long-lasting operation that off-brand units frequently cannot match. Installation is an easy repair for the careful DIYer: disconnect power, safely discharge the old capacitor with an insulated screwdriver, photograph the terminal wiring, move the leads to the matching terminals, and secure the new capacitor in its bracket — usually under 20 minutes. Verify the power is off before touching any terminal. Genuine OEM means guaranteed fit and rating. In stock — orders before 3PM CST ship same day.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model N6D48NG480100?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model N6D48NG480100. 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 N6D48NG480100?
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?
