OEM Carrier Flame Sensor LH680013 for Model PG9MAB060120ABSA

This is the genuine OEM replacement flame sensor (part number LH680013) for the Carrier PG9MAB060120ABSA gas furnace. The flame sensor, also called a flame rod, is a critical safety component that detects the presence of a burner flame during the ignition sequence. It sends a small microamp electrical signal to the control board to confirm combustion. When the sensor fails — typically due to oxidation or carbon buildup on the rod — the furnace will light, run for 5 to 8 seconds, then shut down and go into a safety lockout. Replacing the flame sensor is one of the most common furnace repairs and is almost always the cause of a "starts then shuts off" symptom.

• Specs: OEM part number LH680013 | Factory-matched flame rod material and geometry | Correct microamp signal output for Carrier IFC control board | Direct plug-and-play replacement — no modifications needed
• OEM vs Generic: The OEM LH680013 sensor is manufactured to exact Carrier factory tolerances for rod length, ceramic insulator quality, and signal consistency. Generic sensors can produce unstable microamp readings that trigger nuisance lockouts or shorten control board life.
• Install difficulty: 2/5 — Turn off gas and 120V power before servicing. Tools needed: 1/4" or 5/16" hex driver, fine steel wool or light sandpaper (to clean rod if reusing), multimeter (to verify microamp output). Disconnect the single wire connector, remove the mounting screw, swap the sensor, and reconnect. Always verify flame signal with a meter after installation.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
