The flame sensor uses ionization\/rectification to detect the presence of a burner flame during each heating cycle. When the burner lights, the flame generates a small DC microamp signal through the rod; the control board reads this signal as confirmation that combustion is occurring. If the sensor is absent, fouled with oxide buildup, or failed, the board will shut off the gas valve within 5–8 seconds as a safety precaution — resulting in a no-heat lockout condition that typically repeats on every call for heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 48GS400192 | OEM Carrier replacement | 90° rod angle | Includes mounting hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part — factory-matched rod material, coating, and bracket geometry ensure accurate microamp signal output and reliable board communication.
