The flame sensor is a critical safety component: after the igniter fires the burner, the sensor's rod detects the presence of flame via electrical rectification\/ionization and sends a confirming signal back to the control board. When it fails or becomes coated with oxidation, the board receives no flame signal and shuts off the gas valve within 5–8 seconds of ignition — resulting in repeated short-cycle lockouts and a no-heat call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90-degree flame sensor with mounting bracket | Approx. rod length 1.6\" | Overall dimensions: 4.9\" × 1.75\" | OEM part number 48GS400192 | Genuine Carrier replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the factory OEM sensor, matched to Carrier's exact rectification current thresholds.
