The flame sensor — also called a flame rod — is a safety device mounted in the burner assembly that detects whether a flame is actually present after the igniter fires. It does this by passing a small electrical current through the flame; if the signal is not detected within a few seconds, the control board shuts off the gas valve to prevent unburned gas buildup. When the sensor fails or becomes coated with oxidation, the most tell-tale symptom is a system that ignites and then shuts off after just \u003cstrong\u003e5 to 8 seconds\u003c\/strong\u003e, often cycling through 3 lockout attempts before going into hard lockout and triggering a fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number 48GS400192 | Factory-matched rod diameter and insertion length | Compatible with Carrier-branded packaged unit burner assemblies | Direct plug-and-play replacement — no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e The OEM sensor ensures the exact rod alloy composition, insulator ceramic grade, and terminal connector type specified by Carrier engineering. Generic flame sensors may use inferior rod coatings that oxidize faster, causing repeat nuisance shutdowns and premature control board wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off gas and power at the disconnect before beginning. Tools needed: 1\/4\" or 5\/16\" nut driver, needle-nose pliers, and a soft wire brush to clean the mounting bracket. Do not handle the ceramic insulator with bare hands — skin oils accelerate ceramic degradation.
