Cracked ceramic insulators, eroded electrode tips, and an incorrect spark gap are typical causes of ignition failure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Ignition components must have the exact electrode geometry, gap, and mounting to fire reliably and align with the burner.
