OEM Carrier Flame Sensor LH680013 for Model PG9MAB036080ABSA

This OEM flame sensor (part number LH680013) is the factory-specified replacement for the Carrier PG9MAB036080ABSA gas furnace. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It detects the presence of a flame by passing a small electrical current through the flame itself. When the sensor becomes coated with oxidation or simply fails, the furnace control board cannot verify ignition and will shut off the gas valve within 5–8 seconds as a safety precaution, causing the furnace to lock out after repeated attempts.

• Specs: OEM part number LH680013 | Factory-matched rod diameter and bracket geometry | Correct lead wire length and connector for the PG9MAB036080ABSA control board interface
• OEM vs Generic: OEM flame sensors carry the exact metallurgical composition and coating specified by Carrier engineering. Generic sensors may use inferior rod alloys that oxidize faster, leading to nuisance lockouts and premature replacement — especially in high-cycle heating seasons.
• Install difficulty: 2/5 — Turn off power and gas supply before beginning. Tools needed: 1/4" hex driver or nut driver, fine steel wool or emery cloth (to clean rod if reusing), multimeter. Disconnect the single wire connector, remove the mounting screw, and swap sensors. Tip: lightly sand the rod with fine steel wool before installing new sensor to confirm that oxidation — not a failed sensor — was the root cause.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
