During every heating cycle, the control board energizes the igniter at 120V, heating the element to over 2,000°F to ignite the gas burners. When the igniter fails — through cracking, carbon buildup, or electrical burnout — the furnace attempts ignition, fails, and locks out, leaving you with no heat. Typical symptoms include the inducer starting normally, followed by a lockout error code after one to three failed ignition attempts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V AC | 5 Amp draw | Silicon carbide element | OEM part number LH33ZS004 | Direct factory replacement — no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier igniters are manufactured to precise resistance and thermal-cycling tolerances. Generic igniters frequently fail prematurely due to inconsistent silicon carbide density, causing nuisance lockouts and compounding the original no-heat complaint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Power down and lock out the furnace before starting.
