Listed under two Carrier part numbers — \u003cstrong\u003e329491-401\u003c\/strong\u003e (Gasket Ignitor) and \u003cstrong\u003eLH33ZS004\u003c\/strong\u003e (Hot Surface Ignitor) — this is the direct, drop-in replacement specified in Carrier service literature. The igniter functions by heating to extreme temperatures and glowing bright orange to ignite the gas burner on every call for heat. When it cracks, weakens, or fails entirely, the furnace will attempt ignition, fail to light, and go into lockout — leaving you with no heat. Replacing a failed igniter promptly restores full heating function and prevents repeated lockout cycles that stress your control board.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e 329491-401 | LH33ZS004 — Both are valid Carrier OEM references for this igniter assembly, including the factory gasket.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is manufactured to exact Carrier resistance, wattage, and dimensional tolerances.
