The hot surface igniter (HSI) is the silicon-nitride element that glows orange to light the burners on each heat call. This listing covers the complete ignition group: igniter 1176919, igniter mounting bracket 1177210, and the HSI slow-open gas valve assembly 1177204 (36J24510). When the igniter cracks, oxidizes, or fails to reach ignition temperature, the furnace locks out and stops producing heat — the most common no-heat failure on these units.\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\u003eIgniter Part Number\u003c\/td\u003e\n\u003ctd\u003e1176919\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBracket Part Number\u003c\/td\u003e\n\u003ctd\u003e1177210\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValve \/ HSI Part Number\u003c\/td\u003e\n\u003ctd\u003e1177204 (36J24510)\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 \/ Heil \/ Tempstar \/ Comfortmaker\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 for the WFHR040B024A1 furnace and shared across ICP-family WFHR-series 40,000 BTU gas furnaces sold under the Heil, Tempstar, Comfortmaker, and Arcoaire labels.
