The flame sensor — also called a flame rod — uses ionization\/rectification technology to detect the presence of a burner flame during each heating cycle. When the burner ignites, the flame generates a small DC microamp signal that the control board reads as confirmation of combustion. A failed or contaminated sensor causes the board to cut gas flow as a safety measure, resulting in the furnace starting briefly then shutting off within 5–8 seconds, often triggering a lockout fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48GS400192 | 90-degree flame rod with integrated mounting bracket | Compact rod design (~4.9\" L × 1.75\" H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part — factory-matched rod alloy, bracket geometry, and connector type. Aftermarket sensors frequently use inferior rod coatings that degrade faster, causing repeat failures and nuisance lockouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Power down the furnace at the breaker before servicing. Tools needed: 1\/4\" hex driver or nut driver, light-grit emery cloth (to clean rod if reusing), and a multimeter to verify microamp signal post-install. Disconnect the wire lead, remove the single mounting screw, swap the sensor, and reconnect. Total time: under 15 minutes for most technicians.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty against defects.
