OEM Carrier Flame Sensor w/ Wire LH680014 for Model PG8JAA042090AAJA

This is the OEM factory-specified flame sensor with wire harness for the Carrier PG8JAA042090AAJA gas furnace. The flame sensor is a critical safety component in your furnace's Hot Surface Ignition (HSI) system — it detects the presence of a burner flame and signals the control board to keep the gas valve open. When the sensor becomes coated with oxidation or fails entirely, the furnace will ignite briefly and then shut off within 5–8 seconds as the board reads no flame signal, triggering a safety lockout. Replacing the sensor with an OEM part ensures the correct rod geometry, wire lead length, and kanthal rod material rated to withstand temperatures up to 1,800°F.

  • Specs: 45° rod angle | Kanthal flame rod | High-alumina ceramic insulator | Includes wire lead | Replaces LH33WZ515, LH33WZ511, LH680012, LH33WZ517, LH680534
  • OEM vs Generic: OEM sensors meet exact factory tolerances for rod angle and wire gauge. Generic sensors may use inferior rod materials with lower temperature ratings, increasing risk of nuisance lockouts or premature failure.
  • Install difficulty: 2/5 — Turn off gas and power before starting. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect wire lead, remove single mounting screw, insert new sensor, reconnect lead. Total time: 10–15 minutes.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Fits Carrier model PG8JAA042090AAJA and is used across more than 2,600 Bryant and Carrier 80% efficiency furnace models. Always verify your unit's part number on the data plate or wiring diagram before ordering. Need fitment confirmation? Our HVAC parts specialists are ready to verify compatibility before you buy.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PG8JAA042090AAJA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PG8JAA042090AAJA. 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 PG8JAA042090AAJA?
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.
