The spark electrode ignitor generates the high-voltage electrical arc that ignites the gas burner on each heating call. When it fails, the control board typically attempts ignition one to three times before locking out — leaving you with no heat and a fault code on the board. Common failure signs include visible cracking of the ceramic insulator, carbon tracking on the electrode tip, or a bent\/broken ground rod that prevents proper spark gap.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48VL400002 (superseded to 50HJ403022) | Factory Authorized Carrier replacement | L-shaped electrode design | 2¾\" total length | Made in USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM electrodes are manufactured to exact spark-gap tolerances and ceramic insulator ratings.
