The ignitor generates the high-voltage spark that ignites the gas burner on every call for heat. When it fails, the control board typically attempts ignition one to three times before locking out the system — leaving you with a blinking fault code, a cold building, and a blower running with no heat output. Note: OEM part number \u003cstrong\u003e48VL400002\u003c\/strong\u003e has been superseded by Carrier part \u003cstrong\u003e50HJ403022\u003c\/strong\u003e, which is the current factory-authorized direct replacement and is what ships with this listing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Spark electrode (2-rod) design | Ceramic body construction | Includes mounting bracket | Approx. 4.25″ L × 2.95″ W × 1.75″ H | ~0.095 lb | Factory-matched OEM fitment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM electrodes maintain precise gap geometry and ceramic insulation ratings to factory spec.
