OEM Carrier Furnace Flame Sensor for Model GB1AAV036070AFJA

This OEM Carrier flame sensor restores reliable ignition on the GB1AAV036070AFJA gas furnace. The sensor uses flame rectification to confirm the burners have actually lit; if it doesn't detect a flame within a few seconds, the control board shuts off the gas valve as a safety measure. Over time the sensing rod develops a carbon and oxide coating that weakens the microamp signal, causing the furnace to light briefly and then shut down, or to short-cycle repeatedly during a heating call. A new flame sensor delivers a clean, strong signal so your system runs full heating cycles without nuisance lockouts. Manufactured to factory specs, it fits the GB1AAV036070AFJA mounting and connector exactly. Installation is a simple beginner-friendly job: turn off power and gas, remove one mounting screw, unplug the wire, and install the new sensor. Most homeowners finish in about 10 minutes. A frequently overlooked, inexpensive fix for no-heat complaints. Ships same-day when you order before 3PM CST so heat returns fast.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model GB1AAV036070AFJA?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model GB1AAV036070AFJA. 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 GB1AAV036070AFJA?
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.
