The flame sensor is a critical safety component mounted in the burner assembly. When the burner fires, the sensor rod detects the presence of flame via electrical rectification — a small microamp signal that proves to the control board that combustion is active. When this sensor fails or becomes coated with oxidation, the control board cannot confirm flame presence and shuts off the gas valve within 5–8 seconds of ignition, causing the classic \"lights then goes out\" lockout symptom. Repeated lockout cycles can trigger a hard fault code, leaving your home without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 48GS400192 | 90-degree bend with integrated mounting bracket | Factory OEM replacement — no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM sensor is manufactured to exact Carrier rectification tolerances.
