The flame sensor is a critical safety component — a metal rod positioned in the burner flame that passes a small electrical current through the flame to prove ignition to the control board. When the sensor becomes coated with oxidation or carbon buildup, it can no longer accurately detect the flame, causing the furnace to light briefly and then shut down on lockout after 5–8 seconds. Left unaddressed, repeated lockout cycles can stress the control board and igniter.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number LH33WZ009A | Factory flame rod geometry and ceramic insulator | Matched to Carrier LC3:50HE400802 control board signal thresholds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM sensor provides the exact rod length, bend angle, and ceramic insulator rating specified for this unit. Generic sensors may have inconsistent rod positioning relative to the burner flame, leading to nuisance lockouts or premature failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off gas supply and power before beginning.
