The flame sensor is a critical safety component: once the burner ignites, the sensor uses ionization\/rectification technology to detect the presence of a live flame and send a confirmation signal back to the control board. If the sensor is coated with oxidation or has failed entirely, the control board will cut gas flow within 5–8 seconds of ignition, causing the furnace to lock out and cycle repeatedly without producing heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90° mounting angle | Includes integrated mounting bracket | OEM part #48GS400192 | Dimensions approx. 4.9\" L × 1.75\" H × 1.6\" W | Factory-matched signal tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM sensor built to exact factory specifications.
