The ignitor generates the high-voltage spark that ignites the gas burner on every call for heat. When this component fails, the control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with a blower running but no heat output. A failed ignitor is one of the most common causes of a no-heat service call on Carrier packaged rooftop and gas-electric units.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e OEM part 48VL400002 (Spark Electrode Ignitor) | Current OEM successor: 50HJ403022 — direct factory replacement, same fit and function\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Factory OEM igniters are manufactured to exact electrode gap, ceramic insulator grade, and wire harness specifications.
