OEM Carrier Run Capacitor P291-0454 for Model GB1AAV048110AAJA

Keep your furnace blower motor running strong with the genuine OEM Carrier P291-0454 dual run capacitor, built for the Carrier GB1AAV048110AAJA gas furnace. The run capacitor provides the continuous electrical charge that the blower motor needs to start and maintain proper rotation. A weak or failed capacitor causes hard starting, motor humming, overheating, or a blower that won't spin at all, often leading to no airflow and a tripped limit switch. This direct-replacement capacitor matches the exact microfarad (MFD) and voltage rating of the original component, ensuring stable, efficient motor performance and protecting your blower from premature failure. Installation is relatively easy and takes about 15 to 20 minutes; discharge the old capacitor, note the terminal wiring, and connect the new unit. Always cut power at the breaker and use caution, as capacitors hold a charge. Genuine OEM construction means dependable, long-lasting operation you can count on through every heating season. Order before 3PM CST and your capacitor ships same-day from our US warehouse. Shop NationalHVACParts.com for authentic Carrier parts.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model GB1AAV048110AAJA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model GB1AAV048110AAJA. 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 GB1AAV048110AAJA?
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?
