The igniter glows red-hot to light the burners on each heat call, and it is the single most common ignition wear part on this platform. This listing also covers the related ignition components for this model — flame sensor 1172543 (proves flame after ignition) and snap-mount gas valve 1172541 (Honeywell VR8205S) — so you can replace the full ignition path in one order. A cracked or aged igniter causes no-heat, short-cycling, or a furnace that sparks but never lights; a dirty or failed flame sensor causes the burner to light and then drop out after a few seconds (lockout).\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\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\u003c\/td\u003e\n\u003ctd\u003e1172533 — Hot Surface Igniter (HSI)\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\u003eIncluded\u003c\/td\u003e\n\u003ctd\u003e1172543 Flame Sensor, 1172541 Gas Valve (VR8205S)\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\u003eValve\u003c\/td\u003e\n\u003ctd\u003eHoneywell VR8205S Snap-Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eEngineered for the ICP Tempstar Heil Z8MPN075B12A1 furnace and other ICP-family furnaces using this HSI ignition system with the VR8205S gas valve.
