OEM Carrier Flame Sensor LH680534 for Model GB1AAV036045AFJA

This genuine OEM Carrier flame sensor (LH680534) confirms a stable burner flame on every heating cycle, sending a microamp rectification signal to the control board. When the sensing rod oxidizes or cracks, the board can't verify the flame and shuts off gas—causing short-cycling, repeated lockouts, or a furnace that lights then quickly dies. This sensor is an exact direct-fit replacement for the Carrier GB1AAV036045AFJA gas furnace, with the same probe length, bracket, and terminal as the factory part. Installation is easy for most DIY homeowners: shut off power, remove one screw, unplug the spade connector, and swap in the new rod. Cleaning a corroded sensor is only a temporary fix—a worn rod should be replaced to restore reliable starts. The genuine OEM part ensures proper flame rectification and avoids the nuisance faults common with generic rods. In stock and ships same-day when you order before 3PM CST. Bring back safe, dependable heat with the exact flame sensor Carrier built for your furnace.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model GB1AAV036045AFJA?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model GB1AAV036045AFJA. 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 GB1AAV036045AFJA?
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.
