OEM Carrier Flame Sensor LH680534 for Model GB1AAV048111ADJA

This genuine OEM Carrier flame sensor (LH680534) is the safety component that verifies a flame is present after ignition on your GB1AAV048111ADJA gas furnace. It feeds a microamp flame-rectification signal to the control board so the gas valve only stays open during confirmed combustion; a dirty or worn sensor leads to short-cycling, lockouts, and no-heat calls. Manufactured to exact factory specifications for the GB1AAV048111ADJA, it delivers the correct rod resistance and clean signal that aftermarket sensors frequently fail to provide. Installation is easy and DIY-friendly: shut off power and gas, remove the single mounting screw, disconnect the wire lead, and reverse the steps — typically a 10-minute job with a nut driver. We suggest lightly polishing the sensor rod with fine emery cloth during installation. Bring dependable, safe heat back to your home with a part engineered specifically for your furnace instead of a universal stand-in. In stock and ships same-day when you order before 3PM CST, backed by our quality guarantee and HVAC support team.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model GB1AAV048111ADJA?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model GB1AAV048111ADJA. 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 GB1AAV048111ADJA?
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.
