The flame sensor — also called a flame rod or flame electrode — monitors the burner and sends a microamp signal to the control board confirming combustion is present. When the sensor fails or becomes coated with oxidation, the board cannot verify the flame, triggering a safety lockout. The classic symptom: the furnace or packaged unit lights, runs for 5 to 8 seconds, then shuts off and enters lockout — repeating the cycle with no heat delivered.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Direct Spark Ignition (DSI) flame sensor electrode | Factory Authorized Parts (FAP) designation | Replaces LH33WZ003A and LH33WZ001 | For use with LH33WP001 ignitor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part, manufactured to exact factory tolerances for rod length, ceramic insulator quality, and microamp output.
