The igniter is the first component activated in every heating cycle — it heats to over 2,000°F to light the gas burner reliably and safely. When this part fails, the control board will detect a failed ignition attempt and trigger a system lockout, leaving you with no heat. Common symptoms include the inducer motor running normally but the burners never lighting, or the system cycling through ignition attempts before locking out.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Silicon nitride spark electrode igniter | OEM part number \u003cstrong\u003e48GS400168\u003c\/strong\u003e | Factory-matched mounting geometry and lead length | Rated for high-cycle residential and light-commercial applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier igniter built to exact factory tolerances.
