The igniter is the first critical component in your furnace's ignition sequence — the control board energizes it to reach ignition temperature, allowing the gas valve to open and the burners to light. When the igniter fails, the furnace will attempt a heat cycle, fail to establish a flame, and enter a safety lockout — leaving you with no heat. Common symptoms include the inducer motor running normally but the furnace locking out after one or more ignition attempts with no visible glow at the igniter.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Spark electrode igniter design | OEM part number LH33WZ018 | Factory-matched electrical and mechanical specifications for Carrier LC348LC400283 | Correct bracket geometry and wire harness connector for drop-in installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM igniter manufactured to exact factory tolerances. Generic igniters frequently differ in tip geometry, element resistance, and ceramic insulator quality — leading to premature cracking, inconsistent ignition, and shortened service life. OEM ensures first-time reliable light-off every cycle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Turn off gas supply and 24V power before beginning. Tools needed: 1\/4\" and 5\/16\" nut drivers, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots and premature failure.
