OEM Carrier Flame Sensor LH680013 for Model PG9MAA060100ACKA Gas Furnace

This OEM straight flame sensor (part number LH680013) is the factory-specified replacement for the Carrier PG9MAA060100ACKA gas furnace. The flame sensor is a small but critical safety component — a metal rod mounted in the burner assembly that detects the presence of an active flame by passing a small electrical current through the flame itself. When the sensor rod becomes coated with oxidation or residue after years of use, its ability to conduct that signal degrades. The result is a furnace that lights normally, runs for 5–8 seconds, then shuts down and locks out — leaving you without heat. Replacing this OEM sensor restores reliable ignition and eliminates nuisance lockout cycles.

• Part Number: LH680013 | Straight flame sensor rod | OEM Carrier factory part | Also replaces LH33WZ516 and LH33WZ514
• OEM vs Generic: The OEM LH680013 is manufactured to Carrier's exact rod geometry, ceramic insulator length, and connector specification — ensuring correct flame signal microamp readings. Aftermarket sensors may produce marginal readings that cause intermittent lockouts, especially on older control boards.
• Install Difficulty: 1/5 — One of the easiest furnace repairs available. Tools needed: 1/4" hex nut driver. Turn off power and gas, remove the single mounting screw, unplug the wire connector, and swap the sensor. Total time: under 10 minutes for most technicians.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.

Compatibility: Designed for the Carrier PG9MAA060100ACKA gas furnace. This sensor also cross-references to LH33WZ516 and LH33WZ514. Always verify the part number on your existing sensor or the unit's wiring diagram before ordering.
