The ignitor generates the high-voltage spark that ignites the gas burner at the start of every heat cycle. When it fails, the unit will attempt ignition, fail to establish flame, and enter a safety lockout — leaving you with no heat and a blinking fault code on the control board. The original part number \u003cstrong\u003e48VL400002\u003c\/strong\u003e has been superseded by Carrier OEM replacement \u003cstrong\u003e50HJ403022\u003c\/strong\u003e, which ships as the current factory-authorized assembly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e OEM 48VL400002 (superseded) | Current OEM replacement: 50HJ403022 | Spark electrode ignitor assembly | Factory-authorized Carrier part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM ignitor assemblies are precision-gapped and matched to the burner geometry of your Carrier unit.
