During every heating cycle, the control board energizes the igniter to glow at high temperature, igniting the gas burner. When the igniter fails — due to cracking, contamination, or age-related resistance drift — the furnace will attempt ignition, fail to sense a flame, and lock out. The symptom is a system that calls for heat but delivers only cold air, typically with a fault code indicating an ignition failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e LH33ZG001 | OEM Carrier hot surface igniter | Silicon nitride element | Includes bracket and wiring harness | Factory-matched resistance spec for reliable ignition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM silicon nitride igniters maintain precise resistance tolerances, ensuring the control board sees the correct current draw and the element reaches optimal ignition temperature. Aftermarket units often use silicon carbide, which is more brittle and runs hotter, increasing the risk of premature cracking and repeat failures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — De-energize and lock out the unit before starting. Allow the igniter to cool completely if the unit was recently running. Tools needed: 1\/4\" nut driver, flat-head screwdriver, multimeter (to verify resistance, typically 40–90 Ω). Never touch the ceramic element with bare hands — skin oils cause hot spots that crack the element.
