This combination silicon-nitride igniter both lights the burner and serves as the flame-sensing element for the ignition sequence. Silicon-nitride (SK-style) elements are more rugged than legacy silicon-carbide igniters, but they still wear out after repeated thermal cycling and contamination. When the part fails, the furnace either fails to ignite at all or lights briefly and then drops out on flame failure, because the board can no longer prove flame. Symptoms include short-cycling on ignition, repeated lockouts, and no heat. Handle the new element by its base only — oils and dirt on the igniter\/sensor surface degrade both ignition and flame sensing. This OEM HSP restores correct ignition and flame-proving on the first cycle.\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\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e1009524\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter\/Sensor (HSP, Silicon Nitride)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTempstar (ICP \/ Heil)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eBurner Ignition \u0026amp; Flame Sensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFits Model\u003c\/td\u003e\n\u003ctd\u003eT9MPV075F12B1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eDesigned for the Tempstar T9MPV075F12B1 furnace and the matching ICP\/Heil\/Comfortmaker 9-series variable-speed furnaces that use the 1009524 HSP igniter\/sensor.
