The hot surface igniter is the component that glows red-hot to ignite the gas burners on each heating cycle. When it fails, your furnace will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. This kit upgrades your system to the more durable \u003cstrong\u003esilicon nitride (Si₃N₄)\u003c\/strong\u003e element, replacing the older silicon carbide igniter (LH33ZS004) found in many 33\" tall Carrier furnace models.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120 VAC | Silicon Nitride flat igniter | Steady-state current: 0.8–2.0 A | Cold resistance: 34–64 Ohms @ 75°F | Time to 1800°F: \u0026lt;17 seconds | Max temp: 2732°F (1500°C) @ 132 VAC | Kit includes OEM mounting bracket, OEM connector, and high-temperature wire nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory-genuine kit is engineered to exact Carrier tolerances. Generic igniters often use lower-grade ceramic blends with wider resistance variance, increasing the risk of premature cracking and nuisance lockouts. The OEM silicon nitride element is significantly more crack-resistant than the original silicon carbide design it replaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — This is a straightforward swap suitable for experienced DIYers and technicians alike. Tools needed: ¼\" nut driver, needle-nose pliers, voltage tester. Always shut off gas supply and disconnect power before servicing. Allow the old igniter to cool completely before handling — silicon nitride is brittle and must not be touched with bare hands (skin oils cause hot spots and cracking). Use the included bracket and harness for a clean, plug-and-play installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM manufacturer warranty.
