The igniter is a critical component in the furnace ignition sequence: on every call for heat, the control board energizes the igniter, which glows incandescent to ignite the gas burner. When it fails — due to cracking, oxidation, or an open circuit — the furnace will attempt ignition, fail to establish a flame, and go into lockout mode, leaving you with no heat. Symptoms include a furnace that clicks on, runs the inducer, but never produces heat, often triggering a fault code on the control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e LH33ZS004 (Hot Surface Ignitor) | 329491-401 (Gasket Ignitor kit) — factory-matched to Carrier PG9MAA048100AFKA specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM igniters are manufactured to exact resistance and geometry tolerances.
