The spark electrode ignitor generates a precisely timed high-voltage spark to ignite the burner assembly at the start of every heat cycle. When this component fails, the control board will attempt ignition, detect no flame, and trigger a hard lockout — leaving the unit with no heat output. Typical failure symptoms include a clicking ignition attempt followed by an immediate shutdown, a blinking fault code on the control board, or a unit that runs the inducer but never lights the burner.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48VL400002 (Carrier factory original) | Superseded\/direct replacement: 50HJ403022 — both are genuine OEM Carrier assemblies meeting original factory specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM spark electrode igniters are manufactured to exact gap tolerance and ceramic insulator ratings.
