The flame sensor — also called a flame rod — is a critical safety component that uses ionization\/rectification technology to verify that a burner flame is present during each heating cycle. When the sensor detects no flame signal (or a degraded signal due to oxidation or carbon buildup), the furnace control board initiates a safety lockout, shutting the system down to prevent unburned gas accumulation. A failing flame sensor is one of the most common causes of a furnace that lights briefly and then shuts off after just 5 to 8 seconds.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90° rod angle with factory mounting bracket | Flame rod length approx. 1.6 in. | Overall dimensions approx. 4.9 in. × 1.75 in. | Single-wire connection | OEM part #48GS400192\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, manufactured to exact factory tolerances for rod alloy composition and geometry. Generic flame sensors may exhibit inconsistent microamp output, causing nuisance lockouts or premature failure — especially in high-efficiency condensing furnaces with sensitive control boards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — A straightforward repair for most DIYers with basic tools.
