The spark electrode generates the high-voltage arc that ignites the gas burners during each heating cycle. When the ignitor fails or becomes fouled, the control board will attempt ignition, fail to detect a flame, and lock out the unit — leaving you with a blower running but zero heat output. Common symptoms include repeated ignition attempts followed by a lockout fault code, intermittent heating, or a complete no-heat condition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e 48GS400168 (active) | 48VL400002 (superseded, discontinued Jan 2024) — this listing ships the current active OEM replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Factory-authorized Carrier spark electrodes are manufactured to exact gap, ceramic insulator, and connector specifications.
