OEM Carrier Flame Sensor w/ Wire LH680014 for Model GB1AAV048091ACJA

This is the factory OEM replacement flame sensor with wire harness for the Carrier GB1AAV048091ACJA gas furnace. The flame sensor is a safety rod that detects the presence of a burner flame by passing a small electrical current through the flame itself. When the sensor becomes coated with oxidation or fails entirely, the furnace control board cannot confirm ignition and will shut down the gas valve within 5–8 seconds of startup — typically locking out after 3 attempts. This is one of the most common causes of a furnace that "lights then shuts off."

  • Specs: OEM flame sensor rod with pre-attached wire lead | Factory-matched to Carrier GB1AAV048091ACJA control board signal thresholds | Direct plug-in connector for hassle-free installation | OEM Part Number: LH680014
  • OEM vs Generic: OEM sensors are calibrated to the exact microamp detection range required by the Carrier control board. Generic sensors may produce borderline readings that cause nuisance lockouts or intermittent heating failures, especially as they age.
  • Install difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect the wire lead, remove the single mounting screw, swap the sensor, and reconnect. Tip: do not touch the ceramic insulator or rod with bare hands — skin oils accelerate oxidation.
  • Warranty: 1-year OEM factory warranty. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed specifically for the Carrier GB1AAV048091ACJA gas furnace. Verify your existing part number against LH680014 before ordering. If you're unsure, check the control board wiring diagram inside your furnace door or contact our fitment team — we confirm compatibility before you buy. In stock and ready to ship today.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier GB1AAV048091ACJA?
Yes. This is the factory-specified OEM flame sensor for the Carrier GB1AAV048091ACJA. 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 GB1AAV048091ACJA?
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.
