The current superseding part number is \u003cstrong\u003e50HJ403022\u003c\/strong\u003e — all are fully cross-compatible and factory-authorized. The spark electrode ignitor generates the precisely timed high-voltage spark that ignites the gas burner on each heating cycle. When this component fails or becomes fouled, the control board will attempt ignition, fail to prove flame, and lock out the unit — leaving you with a system that runs the inducer but delivers no heat. This is one of the most common no-heat diagnoses on Carrier packaged rooftop and gas-electric units.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e 48VL400002 | 48GS400168 | Superseded by 50HJ403022 — all factory-authorized designations for this ignitor assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM spark electrodes are manufactured to exact gap spacing and ceramic insulator ratings specified by Carrier engineering.
