The ignitor is a critical component in the furnace ignition sequence — it generates the high-voltage spark that ignites the gas burners during each heating cycle. When this part fails, the control board will attempt ignition, detect no flame, and trigger a safety lockout, leaving your system with no heat. Common symptoms include repeated ignition attempts with no burner light-off, error codes indicating ignition failure, and the system locking out after 2–3 tries.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48VL400002 | Current Replacement P\/N: 50HJ403022 | Factory Authorized Parts™ — exact fit, no modification required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM igniters are manufactured to Carrier's exact spark gap, electrode material, and bracket geometry specifications.
