The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It generates a small microamp current in the presence of a flame, signaling the control board that combustion is confirmed. When the sensor becomes coated with oxidation or carbon deposits, or fails entirely, the control board cannot verify a flame and will shut off the gas valve — typically 5 to 8 seconds after ignition — to prevent unburned gas from accumulating. The result: your furnace lights briefly, then locks out, leaving you without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number 50HJ401431 | Factory-matched flame rod geometry and ceramic insulator | Correct microamp output for Carrier IFC control board compatibility\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier component. OEM flame sensors are factory-calibrated to produce the exact microamp signal your control board expects. Aftermarket sensors can read low, causing nuisance lockouts even when the burner is functioning correctly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before servicing. Tools needed: 1\/4\" or 5\/16\" hex driver (to remove the sensor mounting screw), emery cloth or fine steel wool (to clean rod if reusing), and a multimeter with microamp capability to verify signal after install. Always shut off the furnace at the disconnect before working in the burner compartment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
