The hot surface igniter is a critical component in the furnace ignition sequence — the control board energizes the igniter, which heats to temperatures exceeding 1,800°F to light the burner. When this part fails, the system will attempt ignition, fail to establish flame, and enter a safety lockout, leaving you with no heat. Common failure symptoms include error codes indicating ignition failure, the furnace cycling on and off repeatedly, or a complete no-heat condition after the inducer starts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Spark electrode igniter | OEM part number 48GS400168 | Factory-matched geometry and ceramic insulator | Designed for Carrier packaged gas\/electric systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine OEM Carrier igniter — factory-matched mounting dimensions, electrode gap, and ceramic composition. Generic igniters can have inconsistent electrode gaps and lower-grade ceramics, leading to premature cracking and repeat failures, especially under thermal cycling stress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Turn off gas supply and 24V control power before servicing.
