On a call for heat, the igniter control board (PN 1186861) sends voltage to the igniter (PN 1177663), which glows red-hot to ignite the gas as the valve opens. Hot surface igniters are brittle and wear out with every heating cycle — the silicon-carbide or nitride element develops hairline cracks, oxidizes, and eventually fails to reach ignition temperature. The classic symptom is a furnace that goes through its pre-purge but never lights, or one that locks out after several failed ignition attempts. Replacing the igniter and its control board together restores reliable, on-demand ignition.\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\u003e1177663 (igniter), 1186861 (igniter control board)\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\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP \/ Heil \/ Tempstar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eBurner ignition on heat call\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eOEM, model WPG4484115RKA1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eFactory-correct hot surface igniter and igniter control board for the ICP \/ Tempstar \/ Heil WPG4484115RKA1 gas-heat package unit.
