OEM Carrier Flame Sensor LH680013 for Model PG9MAA036060ACKA

This is the genuine OEM flame sensor (part number LH680013), factory-specified for the Carrier PG9MAA036060ACKA gas furnace. The flame sensor is a critical safety component — it detects the presence of a burner flame via electrical current conduction through the flame rod and signals the integrated furnace control (IFC) board to keep the gas valve open. When the sensor fails or becomes coated with oxidation, the IFC board cannot confirm flame and will shut down the burner as a safety precaution, typically within 5–8 seconds of ignition. The result: the furnace lights briefly, then locks out — often requiring a manual reset.

• Specs: OEM flame rod sensor | Factory-matched resistance and rod geometry | Designed for natural gas and propane operation | Direct plug-in connector for Carrier IFC board
• OEM vs Generic: The OEM LH680013 meets Carrier's exact rod alloy and ceramic insulator specifications, ensuring reliable microamp current signal to the control board. Generic sensors can have inconsistent rod coatings that degrade faster and trigger nuisance lockouts.
• Install difficulty: 2/5 — Turn off power and gas before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect the harness connector, remove the single mounting screw, swap the sensor, and reconnect. Light a test cycle to confirm normal operation.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.
