The flame sensor — also called a flame rod — is a safety-critical component that monitors the burner flame during every ignition cycle. Using the principle of flame rectification, it passes a small current through the burner flame and signals the control board that combustion is confirmed. When the sensor fails or becomes coated with oxidation, the control board cannot verify flame presence and shuts off the gas valve as a safety measure — typically within 5 to 8 seconds of ignition. The result: your system lights briefly, then locks out, cycling repeatedly without producing sustained heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part No. 50HJ401431 | Stainless steel sensing rod | Alumina-coated probe for corrosion resistance | Dimensions approx. 2.9\" W × 4\" D × 1.75\" H | Compatible with 24V AC control circuits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a factory-matched Carrier OEM sensor with calibrated probe geometry and coating — not an aftermarket substitute. Generic flame sensors can have mismatched rod angles, incorrect bracket hole spacing, or lower-grade coatings that degrade faster, leading to repeat nuisance lockouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — A straightforward single-screw bracket removal. Tools needed: 1\/4\" or 5\/16\" nut driver, fine steel wool or emery cloth (to lightly clean the rod if reusing bracket hardware), and a multimeter to verify microamp signal post-install.
