On a call for heat the control board energizes the igniter; it glows white-hot to ignite the gas as the valve opens. Hot surface igniters are brittle silicon-carbide or silicon-nitride elements that crack from age, thermal cycling, or being touched with bare fingers — and a cracked igniter is the single most common no-heat failure on this style of furnace. Symptoms include the inducer and igniter sequence starting but no flame, or a hard lockout after several failed ignition attempts.\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\u003eOEM Part Number\u003c\/td\u003e\n\u003ctd\u003e1177663 (igniter), 1186861 (igniter control board)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Type\u003c\/td\u003e\n\u003ctd\u003eHot Surface Igniter\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\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eBurner ignition for gas heat section\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHandling\u003c\/td\u003e\n\u003ctd\u003eDo not touch the element — oils cause premature failure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFits Model\u003c\/td\u003e\n\u003ctd\u003eWPG4364060LKB1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eDirect-fit replacement for the ICP WPG4364060LKB1 packaged gas\/electric unit and compatible across Tempstar, Heil, and Comfortmaker WPG-series furnaces using this hot surface ignition system.
