OEM Carrier Run Capacitor P291-0454 for Model GB1AAV036045ABJA

This OEM Carrier run capacitor (P291-0454) keeps the blower motor on your Carrier GB1AAV036045ABJA furnace running with steady torque and efficiency. By storing and discharging energy on each cycle, it maintains the phase shift the motor needs to spin smoothly; a degraded capacitor leads to a motor that hums but won't start, weak airflow, overheating, or nuisance thermal trips. Matched to the precise microfarad and voltage rating Carrier specifies for this furnace, this genuine capacitor restores full motor performance and helps prevent costly motor burnout. Installation is easy and takes about 15 minutes: disconnect and discharge the old capacitor, note the lead positions, transfer the wires, and clamp the new unit in place. Always cut power and discharge before handling. Choosing OEM ensures exact sizing and dependable service life. In stock and ready to ship — orders placed before 3PM CST go out the same day. Keep your blower cool, quiet, and reliable with the precise capacitor Carrier designed for this model.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model GB1AAV036045ABJA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model GB1AAV036045ABJA. 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 GB1AAV036045ABJA?
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?
