OEM Carrier Flame Sensor LH680534 for Model GB3AAV036070AEJA

Keep your Carrier furnace firing safely with this genuine OEM flame sensor (LH680534). The flame sensor confirms that the burner has actually ignited; when its surface oxidizes or cracks, the control board can no longer detect flame and shuts the gas valve within seconds — the classic symptom of a furnace that lights, runs briefly, then shuts off and locks out. This OEM rod is built to the precise length, mounting pattern, and electrical signal characteristics required by the Carrier GB3AAV036070AEJA gas furnace, restoring a strong, stable flame-rectification signal. Replacing it is one of the easier furnace repairs — usually 15 minutes: shut off power and gas, remove one mounting screw, unplug the lead, and install the new sensor. Avoid bending the rod and keep it clean during install. A new sensor restores reliable, uninterrupted heat and ends frustrating lockouts. In stock and ships same-day when ordered before 3PM CST, getting heat back to your home or jobsite quickly.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model GB3AAV036070AEJA?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model GB3AAV036070AEJA. 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 GB3AAV036070AEJA?
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.
