The flame sensor (also called a flame rod) monitors burner ignition by detecting a small microamp current through the flame itself. When the sensor rod oxidizes or becomes coated with residue, it can no longer read the flame accurately — causing the furnace control board to shut off the gas valve as a safety measure. The result: your furnace lights, runs for 5–8 seconds, then shuts off and locks out. Replacing this low-cost OEM sensor is one of the most common furnace repairs and restores normal heating operation immediately.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90° mounting angle | Includes mounting bracket | Factory-matched rod length and composition | OEM part number 48GS400192\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part with exact rod geometry, alloy composition, and bracket fit.
