OEM Carrier Straight Flame Sensor LH680013 for Model PG9MAB036060ACSA

This OEM straight flame sensor (part number LH680013) is the factory-specified replacement for the Carrier PG9MAB036060ACSA gas furnace. The flame sensor is a small but mission-critical component: its flame rod extends into the burner assembly and passes a micro-amp current through the flame to confirm ignition. When the sensor is coated with oxidation or worn out, the control board cannot verify a flame is present and will shut off the gas valve within 5–8 seconds of ignition — leaving you with a furnace that lights briefly then locks out repeatedly.

• Specs: Straight flame rod configuration | OEM part number LH680013 | Also replaces LH33WZ516 and LH33WZ514 | Factory-matched micro-amp signal output
• OEM vs Generic: This OEM sensor meets Carrier's exact rod geometry and insulator spec. Aftermarket sensors can suffer from inconsistent micro-amp output, causing nuisance lockouts even after installation — use OEM for a verified fix.
• Install Difficulty: 1/5 — One of the easiest furnace repairs. Turn off power and gas before beginning. Tools needed: 1/4" hex driver or flathead screwdriver. Disconnect the single wire connector, remove one mounting screw, swap the sensor, reconnect, and test. Total job time: under 15 minutes.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
