The flame sensor is a critical safety component that confirms the presence of a flame in the burner assembly. It generates a small microamp signal through the flame rod — if that signal is absent or too weak (typically due to oxidation on the rod tip), the integrated furnace control board will cut gas flow within 5–8 seconds as a safety lockout. The result: your furnace lights briefly, then shuts off repeatedly, often with a fault code indicating \"flame sense\" or \"failed ignition.\"\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Carrier flame sensor rod | Replaces part numbers \u003cstrong\u003eLH33WZ521\u003c\/strong\u003e (sensor only) and \u003cstrong\u003eLH680534\u003c\/strong\u003e (sensor with lead harness) | Factory-matched microamp output | Fits 96% AFUE two-stage burner assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM sensors use factory-spec alloy rods with exact geometry for proper flame contact and signal strength.
