The hot surface igniter (HSI) is energized at the start of each heating cycle and glows white-hot to ignite the gas at the burners. It is one of the most common furnace failure points because the silicon-carbide or silicon-nitride element grows brittle with thousands of heat cycles and eventually cracks. A failed igniter is the leading cause of no-heat calls: the inducer runs, the gas valve opens, but the burners never light, and the furnace locks out after several retries.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Part Number\u003c\/td\u003e\n\u003ctd\u003e1176919 (Igniter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncluded Bracket\u003c\/td\u003e\n\u003ctd\u003e1183455 (Bracket, Igniter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelated Part\u003c\/td\u003e\n\u003ctd\u003e1176929 (Valve N HSI Snap WR 36J24618)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter (HSI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Tempstar \/ Heil\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eGas Furnace Ignition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDirect OEM fit for the ICP Tempstar Heil WFML110C066B3 furnace and shared across ICP-family gas furnaces using this hot surface igniter and bracket assembly.
