OEM Carrier Straight Flame Sensor LH680013 for Model PG9MAB048060ACSA

This is the factory OEM straight flame sensor (part #LH680013) for the Carrier PG9MAB048060ACSA gas furnace. The flame sensor — also called a flame rod or flame rectifier — is a safety device that monitors whether a flame is actually present after the igniter fires. It passes a small electrical current through the burner flame; if no flame is detected within a few seconds, the control board shuts down the gas valve to prevent unburned gas from accumulating. When the sensor becomes coated with oxidation or carbon buildup, or the rod itself fails, the furnace will light briefly and then shut off after 5–8 seconds, cycling repeatedly without producing heat. Replacing this sensor is one of the most common and cost-effective furnace repairs.

  • Specs: Straight rod design | Probe length: 3 inches | High-quality ceramic insulator | Factory-matched electrical resistance tolerance | OEM part #LH680013
  • OEM vs Generic: This genuine Carrier OEM sensor meets exact factory resistance and ceramic insulation specs. Aftermarket sensors can have inconsistent rod coatings and looser tolerances, causing nuisance shutdowns or premature re-failure.
  • Install difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" hex driver or nut driver, wire connector. Locate the sensor on the burner assembly, disconnect the single wire harness, remove one mounting screw, and install the new sensor. Always verify correct seating of the ceramic insulator. Takes approximately 15–30 minutes.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG9MAB048060ACSA gas furnace. Also fits select Carrier 58MCA series and related Bryant/Payne furnace models that use the LH680013 straight flame sensor. Always cross-reference your existing part number or data plate before ordering. Have a fitment question?

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PG9MAB048060ACSA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PG9MAB048060ACSA. 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 PG9MAB048060ACSA?
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.
