The hot surface igniter is the component responsible for igniting the gas burner at the start of every heating cycle. On a call for heat, the control board energizes the igniter, which heats to ignition temperature before the gas valve opens. When the igniter fails — due to hairline cracks, oxidation, or thermal fatigue — the burner never lights, and the control board enters a safety lockout. Common symptoms include: the inducer fan running normally followed by a hard lockout, an error code indicating failed ignition, or repeated restart attempts with no heat output.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Spark electrode igniter design | Factory OEM part number 48GS400168 | Drop-in replacement — no modifications required | Engineered to factory ignition timing and surface temperature specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier OEM igniter, manufactured to exact geometry and thermal resistance specs.
