The flame sensor — also called a flame rod — is a critical safety component that detects whether a burner flame is actually present after ignition. It does this by passing a small microamp current through the flame itself. When the sensor is fouled with oxidation or carbon buildup, or has failed entirely, the control board cannot confirm combustion and will shut off the gas valve within 5 to 8 seconds of ignition — leaving you with a system that lights briefly and then locks out on a fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 50HJ401431 | OEM Carrier replacement | Stainless steel sensing probe with alumina-coated rod for corrosion resistance and high-temperature durability\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory-genuine OEM sensor is calibrated to the exact microamp sensitivity threshold required by the Carrier control board.
