OEM Carrier Flame Sensor LH680013 for Model PG9MAA024040AAKA

This is the OEM factory-specified flame sensor (part #LH680013) for the Carrier PG9MAA024040AAKA gas furnace. The flame sensor is a straight flame-rod assembly that monitors the presence of a burner flame during each heating cycle. When the control board calls for heat, the igniter lights the burners, and the flame sensor passes a small electrical current through the flame to confirm ignition. A failed or contaminated sensor cannot confirm the flame signal, causing the control board to shut off the gas valve as a safety measure — typically resulting in the furnace starting and then shutting down after 5–8 seconds, repeating in a lockout loop.

  • Part Number: LH680013 | Straight flame rod design | Factory OEM replacement for Carrier PG9MAA024040AAKA gas furnaces
  • OEM vs Generic: This OEM part is manufactured to exact Carrier factory tolerances for rod geometry, insulator material, and lead wire length — ensuring proper flame signal strength and reliable microamp readings. Generic sensors may produce marginal signals that cause nuisance lockouts.
  • Install Difficulty: 2/5 — Turn off gas and power at the breaker before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, multimeter (optional, to verify microamp signal). Locate the sensor in the burner assembly, disconnect the single wire connector, remove one mounting screw, and swap in the new sensor. Always clean the burner area of debris before reinstalling.
  • Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse — order by 3 PM local time.

Compatibility: Directly replaces OEM part number LH680013 (also cross-references LH33WZ516, LH33WZ514) for the Carrier PG9MAA024040AAKA gas furnace. Verify your existing sensor is the straight-rod type and confirm part number on your unit's wiring diagram or parts list before ordering. Have questions about fitment?

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PG9MAA024040AAKA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PG9MAA024040AAKA. 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 PG9MAA024040AAKA?
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.
