The flame sensor (also called a flame rod) monitors the gas burner flame by detecting micro-ampere ionization current through the flame. When it detects a valid flame, it signals the integrated furnace control (IFC) board to keep the gas valve open. When the sensor fails — typically due to carbon buildup or a cracked ceramic insulator — the control board cannot confirm ignition and will cut gas flow within 5 to 8 seconds of startup, causing a no-heat lockout condition that repeats on every call for heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e LH33WZ005 | Factory Authorized Parts (FAP) | Carrier OEM assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Lead:\u003c\/strong\u003e 64-1\/2\" Teflon-insulated lead wire included — no splicing required for a direct drop-in swap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM flame sensors maintain precise rod geometry and ceramic insulation ratings.
