OEM Carrier Run Capacitor P291-0454 for Model GB1AAV048091ADJA

Keep your blower motor running strong with this OEM Carrier run capacitor (P291-0454) for the GB1AAV048091ADJA gas furnace. The run capacitor delivers the steady phase shift the motor needs to start smoothly and run efficiently, reducing amp draw and heat. A weak or bulging capacitor causes hard starts, humming, overheating, or a blower that won't spin — and it's one of the most common HVAC failures. This direct-fit replacement matches the original microfarad and voltage ratings for the GB1AAV048091ADJA, so performance returns to factory spec. Installation is an easy DIY repair: turn off power, discharge the old capacitor, note the terminal wiring, and swap in the new one. Most jobs take 15 minutes with a screwdriver and nut driver. Using a genuine OEM capacitor protects your motor and extends equipment life versus cheap generics. In stock and ships same-day when you order before 3PM CST, getting comfort restored to your home quickly and affordably.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model GB1AAV048091ADJA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model GB1AAV048091ADJA. 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 GB1AAV048091ADJA?
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?
