The spark electrode generates the high-voltage arc that ignites the gas burner on every call for heat. When this component fails, the control board will attempt ignition, detect no flame, and lock out — leaving you with a unit that attempts to start, clicks repeatedly, then shuts down and displays a fault code. Replacing the ignitor with the correct OEM assembly restores reliable, first-attempt ignition and prevents nuisance lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part # 48VL400002 (superseded by 50HJ403022) | L-shaped electrode design | Ignitor length to L: 1 3\/8\" | Total ignitor length: 2 3\/4\" | Country of Origin: USA | Factory-matched gap and ceramic insulation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM electrodes maintain precise spark gap geometry and use factory-grade ceramic insulators. Generic igniters often have inconsistent gap tolerances, leading to weak sparks, delayed ignition, and accelerated wear on the gas valve and control board.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before beginning.
