The hot surface igniter (HSI) glows red-hot on a thermostat call and ignites the burner gas as the gas valve opens. It works alongside the flame sensor (1172543) that proves the flame and the snap-acting gas valve (1172541, Honeywell VR8205S) that meters fuel — together these make up the furnace's ignition system. The igniter is the most frequently replaced ignition component because its element is brittle and degrades with every heating cycle. A cracked or burned-out igniter is the leading cause of a furnace that clicks, draws but never lights, and locks out on failed ignition.\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\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1172533\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\u003eRelated Flame Sensor\u003c\/td\u003e\n\u003ctd\u003e1172543\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelated Gas Valve\u003c\/td\u003e\n\u003ctd\u003e1172541 (Honeywell VR8205S)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eFurnace burner ignition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDesigned for the ICP Tempstar Heil X8MPN075B12A3 gas furnace and other N-series furnaces using the same HSI ignition platform.
