The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. When the burner fires, the sensor uses an ionization\/rectification technique to detect the presence of flame and sends a microamp signal to the control board confirming ignition. If the sensor is coated with oxidation or has failed, the control board receives no signal, assumes a failed ignition, and shuts off the gas valve — typically within 5 to 8 seconds of startup. The result: a furnace that lights briefly, then locks out on a no-flame fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 48GS400192 | OEM Carrier genuine replacement | 90-degree mounting bracket included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM sensor is manufactured to exact factory microamp-detection tolerances.
