The ignitor generates the high-voltage spark that ignites the gas burner on each heating call. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that runs its inducer but produces no heat. Common symptoms include repeated ignition lockouts, error codes for ignition failure, and no heat despite the thermostat calling for it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e OEM part number 48VL400002 has been superseded by Carrier part number \u003cstrong\u003e50HJ403022\u003c\/strong\u003e.

Tools needed: 1\/4\" and 5\/16\" nut drivers, needle-nose pliers, and a multimeter to verify spark circuit continuity. Always shut off gas supply and disconnect power at the disconnect before servicing. Handle the electrode tip carefully — ceramic insulators are fragile.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty against defects.
