The flame sensor is a critical safety component: after ignition, it uses ionization\/rectification technology to verify that a burner flame is actively present. If the sensor is fouled, corroded, or failed, the furnace control board will not detect the flame signal and will shut off the gas valve within 5–8 seconds of ignition — resulting in repeated short-cycle lockouts and a cold home. Replacing this sensor is one of the most common and cost-effective furnace repairs available.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e OEM Carrier part #48GS400192 | 90-degree mounting angle | Includes mounting bracket | Approx. dimensions: 4.9\" H × 1.75\" W × 1.6\" rod length | Genuine OEM replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a factory-matched OEM part built to exact Carrier specifications.
