The igniter is the critical first step in every heating cycle — it generates the high-temperature surface or spark that lights the burner gas. When it fails, the furnace or packaged unit will attempt ignition, fail to establish flame, and go into hard lockout, leaving you with a no-heat call and a flashing fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number 48GS400168 | Spark Electrode Ignitor | Factory-matched geometry and electrode gap | Rated for Carrier packaged heating applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the exact OEM Carrier igniter — not an aftermarket approximation.
