The flame sensor — also called a flame rod — is a safety device that confirms a burner flame is present during each ignition cycle. The control board sends a small electrical current through the rod; if a flame is detected, the microamp signal tells the board to keep the gas valve open. When the sensor becomes coated with oxidation or carbon buildup, the signal weakens and the board shuts the furnace down within 5–8 seconds, triggering a fault lockout. Replacing it with a genuine OEM part restores precise factory-specified microamp sensitivity and keeps your furnace running safely all season.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part# 48GS400192 | Flame rod \/ flame sensor | Factory-matched microamp response | Direct plug-in connector for Carrier PY3PNA060090NB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM flame sensors are manufactured to exact Carrier tolerances for rod material, coating, and connector geometry. Generic sensors often exhibit inconsistent microamp output, leading to nuisance shutdowns or, worse, delayed safety shutoff — neither of which is acceptable in a gas appliance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off gas supply and 120V power before beginning.
