The spark electrode ignitor is the critical component responsible for igniting the gas burner during every heating cycle. When this part fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that calls for heat but delivers none. Common symptoms include repeated ignition attempts followed by a hard lockout fault code, or a visible crack or carbon tracking on the ceramic electrode body.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48VL400002 (superseded by Carrier OEM part 50HJ403022) | Factory Authorized Parts designation | Genuine Carrier spark electrode assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM igniters are manufactured to exact Carrier spark gap, ceramic grade, and wire harness specifications.
