The kit centers on igniter part \u003cstrong\u003e1176919\u003c\/strong\u003e, supported by mounting bracket \u003cstrong\u003e1183455\u003c\/strong\u003e and HSI snap-fit valve\/igniter assembly \u003cstrong\u003e1176929 (36J24618)\u003c\/strong\u003e. When the thermostat calls for heat, the furnace control board energizes the hot surface igniter, which glows to roughly 2,000°F and ignites the gas at the burners. Over time the brittle silicon-carbide or silicon-nitride element develops hairline cracks and stops glowing — the most common cause of a furnace that clicks, draws air, but never lights. Replacing the igniter with the correct OEM part restores reliable first-try ignition and prevents repeated lockouts.\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 (Igniter Bracket)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncluded HSI Assembly\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\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\u003eFits Model\u003c\/td\u003e\n\u003ctd\u003eWFMR135D066B3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM Direct Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eEngineered as a direct-fit replacement for the ICP-family WFMR135D066B3 gas furnace and is shared across the Tempstar, Heil, and Comfortmaker variants built on the same chassis.
