The spark electrode ignitor generates the high-voltage spark that ignites the gas burner on each heating call. When the ignitor fails or becomes fouled, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that cycles but delivers no heat. Replacing the ignitor with the correct OEM part restores reliable ignition and prevents nuisance lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e OEM Carrier 48VL400002 | Current superseding part: 50HJ403022 (also replaces 50HJ401430, 50HJ400608) | Factory-authorized genuine Carrier component\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM spark electrodes are matched to the factory gap specification and ceramic insulator rating of your unit.
