On a call for heat, the control board energizes the igniter, which glows white-hot to ignite the gas at the burners. This igniter\/sensor design also assists with flame confirmation during the ignition sequence. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that degrade with every heat cycle and eventually crack or lose the ability to reach ignition temperature. A failed igniter is one of the most common causes of a no-heat call: the inducer runs and the gas valve is ready, but the furnace never lights, or it locks out after several failed ignition attempts.\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\u003e1009524\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter \/ Sensor (HSP SK)\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\u003eIgnition + Flame Sensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eBuilt as a direct OEM replacement for the Tempstar TDE050B12G1 furnace and other ICP-family models (Tempstar, Heil, Comfortmaker, Arcoaire) that use the 1009524 hot surface igniter.
