The spark electrode ignitor generates the high-voltage spark needed to ignite the gas burner at the start of each heating cycle. When the ignitor fails or cracks, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a no-heat call and a fault code. This part is also cross-referenced under the updated Carrier OEM part number \u003cstrong\u003e50HJ403022\u003c\/strong\u003e, which supersedes 48VL400002 and also replaces 50HJ401430 and 50HJ400608.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Spark electrode ignitor assembly | OEM part number 48VL400002 (superseded by 50HJ403022) | Factory-matched spark gap and mounting geometry | Includes bracket and lead wire assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM electrodes maintain precise spark gap tolerances calibrated to your unit's ignition module.
