On a call for heat, the control board energizes the igniter (OEM part 1172533) until it glows white-hot, lighting the main burners as the gas valve opens. A failed igniter is one of the most common no-heat causes: the silicon-nitride element becomes brittle with thermal cycling and eventually cracks, leaving the furnace unable to light. Typical failure symptoms include the furnace running its full ignition sequence with no flame, the igniter glowing weakly or not at all, repeated lockouts after several ignition attempts, or hard cold-start clicking with no burner light. Because this furnace pairs the igniter with a dedicated flame sensor (1172543) and a snap-mount gas valve (1172541 VR8205S), a clean igniter is essential to reliable ignition and proper flame proving.\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 Number\u003c\/td\u003e\n\u003ctd\u003e1172533 (IGNITOR HSI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelated OEM Parts\u003c\/td\u003e\n\u003ctd\u003e1172543 (Flame Sensor), 1172541 (Gas Valve VR8205S)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter, silicon nitride\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\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e120 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFits Model\u003c\/td\u003e\n\u003ctd\u003eX9MPD075F12B1\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 as the factory ignition component for the ICP\/Tempstar\/Heil X9MPD075F12B1 75,000 BTU gas furnace.
