The flame sensor is a critical safety component that uses \u003cstrong\u003eionization\/rectification technology\u003c\/strong\u003e to verify burner ignition during each heating cycle. When the flame sensor fails or becomes coated with oxidation, the furnace control board cannot confirm combustion is present — causing the unit to lock out after just 5–8 seconds of operation. If your furnace lights, runs briefly, then shuts down and repeats the cycle, a failed or fouled flame sensor is almost always the culprit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90-degree angle rod configuration | Includes factory mounting bracket | Dimensions approx. 4.9\" × 1.75\" × 1.6\" | Direct OEM replacement for part #48GS400192\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory-original part is manufactured to Carrier's exact metallurgical and geometric tolerances. Aftermarket sensors can have rod coatings or bend angles that differ from spec, causing nuisance lockouts or false readings that shorten control board life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off gas and power before servicing. Tools needed: 1\/4\" hex driver, fine steel wool or emery cloth (to clean rod if reusing), multimeter (to verify microamp signal). Disconnect the single wire connector, remove one mounting screw, and swap in the new sensor. Job typically takes under 15 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty against defects.
