OEM Carrier Flame Sensor for Model GB3AAV024070ACJA Gas Furnace

This OEM Carrier flame sensor provides the essential safety check that verifies burner flame on your GB3AAV024070ACJA gas furnace, signaling the control board to keep gas flowing only when combustion is confirmed. As the sensor rod accumulates carbon and oxide deposits, its signal weakens, leading to short-cycling, flame-loss lockouts, or a furnace that ignites then drops out moments later. This genuine Carrier replacement is built to the exact rod length and mounting geometry for accurate flame rectification and steady heat. It is a direct fit for the GB3AAV024070ACJA, requiring no modification. Installation is easy and DIY-friendly: turn off power and gas, remove the mounting screw, unplug the wire lead, and seat the new sensor. Handle the rod with a clean cloth to avoid contamination. OEM delivers the proper microamp signal strength that generic sensors frequently fall short of. In stock and ships same-day on orders placed before 3PM CST. Restore reliable, safe ignition with a genuine Carrier flame sensor and keep your furnace running through the cold.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model GB3AAV024070ACJA Gas Furnace?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model GB3AAV024070ACJA Gas Furnace. 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 flame_sensor on my Carrier Model GB3AAV024070ACJA Gas Furnace?
Difficulty: Easy (10–15 min)
Step 1: Turn off power/gas. Step 2: Open furnace panel. Step 3: Locate flame sensor rod near burners. Step 4: Remove single mounting screw. Step 5: Clean rod with 400-grit sandpaper until shiny (or replace). Step 6: Reinstall and tighten. Most common furnace repair — saves $150–$300 vs technician.
My furnace lights then shuts off after a few seconds. Why?
Furnace lights then shuts off after 3–10 seconds = dirty flame sensor in 90% of cases. The sensor can’t detect flame through oxidation buildup. Fix: clean with 400-grit sandpaper (free, 15 min). If cleaning doesn’t work, replace the sensor.
Is this flame_sensor 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 flame_sensor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
