OEM Carrier Flame Sensor LH680534 for Model GB1AAV036055AAJA

This OEM Carrier flame sensor (LH680534) verifies that your burners have ignited and signals the control board to keep gas flowing. Designed for the GB1AAV036055AAJA gas furnace, it relies on flame rectification to produce a small microamp current; when that signal drops, the board closes the gas valve as a safety measure. Over time the sensor rod develops a carbon or oxide film, causing the furnace to fire briefly then shut down repeatedly — the hallmark short-cycling symptom. Installing this genuine factory sensor restores consistent, uninterrupted heat. The OEM part matches your furnace's exact rod length, mounting bracket, and connector for a precise drop-in fit. Installation is easy and DIY-friendly: turn off power and gas, remove the single screw, disconnect the lead, and mount the new sensor — roughly 10 minutes with no special tools. Genuine construction ensures dependable flame detection and longer life than universal rods. In stock and ships same-day when you order before 3PM CST. Fit guaranteed for the GB1AAV036055AAJA furnace.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model GB1AAV036055AAJA?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model GB1AAV036055AAJA. 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 GB1AAV036055AAJA?
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.
