OEM Carrier Straight Flame Sensor LH680013 for Model PG9MAB060080ABSA

This OEM straight flame sensor (part number LH680013) is the factory-specified replacement for the Carrier PG9MAB060080ABSA gas furnace. The flame sensor is a small but critical safety component — it's a metallic rod that detects the presence of an active burner flame by passing a small electrical current through it. If the sensor becomes coated with oxidation or carbon buildup, or fails outright, the furnace control board will not confirm ignition and will shut the gas valve off within 5–8 seconds of each start attempt, causing the unit to lock out after repeated tries. Replacing this sensor is one of the most common and cost-effective furnace repairs available.

• Part Number: LH680013 | Straight flame rod design | Factory-matched geometry and rod metallurgy for accurate microamp signal readings
• OEM vs Generic: This OEM part meets Carrier's exact signal-threshold specifications. Aftermarket sensors may produce lower microamp readings, causing nuisance lockouts even when the burner is functioning correctly.
• Install Difficulty: 1/5 — One of the easiest furnace repairs. Tools needed: 1/4" hex driver or small nut driver. Turn off power and gas before servicing. Unplug the single wire connector, remove one mounting screw, swap the rod, and reconnect. Total time: under 10 minutes.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
