The igniter is a critical component in the heating sequence — upon a call for heat, the control board energizes the igniter, which heats to over 1,800°F to ignite the gas burners. When the igniter fails or cracks, the furnace will attempt to light, fail to establish flame, and enter a safety lockout — leaving you with no heat. Common symptoms include repeated ignition attempts with no flame, error codes indicating ignition failure, or a visibly cracked or broken igniter element.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM Part Number LH33WZ010 | Silicon carbide spark electrode igniter | Factory-matched voltage and wattage | Direct OEM replacement — no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM igniter is manufactured to Carrier's exact electrical and thermal specifications.
