The spark electrode ignitor generates the high-voltage arc that lights the burner on each call for heat. When this component fails, the control board will attempt ignition, detect no flame, and initiate a lockout sequence — leaving you with a no-heat condition and a fault code. Symptoms include repeated clicking with no ignition, or the unit cycling off within seconds of a heat call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Spark electrode ignitor assembly | Factory-matched electrode gap and ceramic insulator | OEM part number 48VL400002 | Superseded by Carrier part 50HJ403022 (same fit and function — confirm fitment at checkout)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM spark electrodes are manufactured to exact gap tolerances and ceramic insulation ratings specified by Carrier.
