The flame sensor — also called a flame rod — uses ionization\/rectification technology to detect the presence of an active burner flame during each heating cycle. When the sensor is fouled with oxidation or has failed entirely, the furnace control board loses confirmation that ignition occurred, triggering a safety lockout. The classic symptom: your furnace lights, runs for 5–8 seconds, then shuts off — repeating 3 times before locking out completely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e 90-degree rod angle | Includes factory mounting bracket | OEM part #48GS400192 | Compact form factor (~4.9\" × 1.75\" × 1.6\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM sensor — not a universal substitute.
