OEM Carrier Run Capacitor P291-3543 for Model GB3AAV036070AFJA

This genuine OEM Carrier run capacitor (P291-3543) provides the steady electrical phase shift your blower or inducer motor needs to start smoothly and run efficiently. A weak or failed capacitor is the most common cause of a furnace motor that hums but won't spin, trips on overload, or short-cycles. This unit is engineered to the exact microfarad and voltage rating required by the Carrier GB3AAV036070AFJA gas furnace, ensuring correct motor torque and long service life. Using an off-spec capacitor can overheat windings and shorten motor life, so matching the OEM part matters. Installation is easy for most DIYers — typically a 15-20 minute job: disconnect power, discharge the old capacitor, note the wire positions, and swap terminals. No special tools beyond a screwdriver and insulated pliers are needed. Restore quiet, reliable heating and avoid a costly motor replacement. In stock and ships same-day when ordered before 3PM CST, so you can get your system back up and running fast.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model GB3AAV036070AFJA?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model GB3AAV036070AFJA. 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 GB3AAV036070AFJA?
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?
