OEM Carrier Flame Sensor w/ Wire LH680014 for Model PG8MAA048090ABJA

This OEM flame sensor with wire harness is the factory-specified replacement for the Carrier PG8MAA048090ABJA gas furnace. The flame sensor is a critical safety component — a metal rod that detects the presence of a burner flame by passing a small microamp current through the flame itself. When the sensor's rod becomes coated with oxidation or mineral buildup, or fails entirely, the furnace control board can no longer confirm ignition and will shut off the gas valve within 5–8 seconds as a safety lockout. The result: the burner lights briefly, then the furnace goes through repeated ignition attempts before locking out entirely.

  • Part Number: LH680014 | Includes factory wire harness | 45-degree rod orientation | High-temperature Kanthal flame rod material | Compatible with HSI (Hot Surface Ignition) systems
  • OEM vs Generic: This OEM unit is built to Carrier's exact microamp sensing threshold and rod geometry. Generic sensors can vary in rod angle and sensitivity, causing nuisance lockouts or delayed shutoff response — a safety concern on any gas appliance.
  • 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 harness, remove the single mounting screw, swap the sensor, and reconnect. Always verify flame signal (microamps) with a multimeter after installation.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PG8MAA048090ABJA gas furnace. Also replaces OEM part numbers LH33WZ515, LH33WZ511, LH680012, and LH33WZ517. Verify your existing part number against your unit's data plate or wiring diagram before ordering. Need help confirming fitment? Our HVAC parts team is standing by.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PG8MAA048090ABJA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PG8MAA048090ABJA. 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 PG8MAA048090ABJA?
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.
