The ignitor is the first critical component in the heating sequence — it generates the spark or surface heat needed to ignite the gas burners on each call for heat. When this part fails, the system will attempt ignition, fail to light, and enter safety lockout mode — leaving you with no heat. Common symptoms include a furnace that clicks or attempts to start but shuts off within seconds, repeated ignition lockout error codes, or a unit that runs the inducer but never produces a flame.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e 2-rod spark electrode assembly | Factory Authorized Parts (FAP) | OEM part number 48GS400168 | Direct drop-in replacement — no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, manufactured to exact factory tolerances for electrode gap, ceramic insulation rating, and lead wire length. Generic igniters often feature inconsistent electrode gaps and inferior ceramic insulators that crack under thermal cycling, shortening service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Straightforward swap.
