It sequences the entire heating cycle — inducer start, pressure-switch proving, hot-surface igniter warm-up, gas-valve timing, flame sensing, and blower on\/off delays — while managing the 24V thermostat signals and safety lockouts. This OEM assembly pairs the circuit board (1178358) with the ignition control module (1177661) so the board correctly drives the igniter and verifies flame. A failed board typically shows up as no ignition, short cycling, blower running constantly, or a flashing diagnostic LED fault code.\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\u003e1178358 (circuit board), 1177661 (ignition control module)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eIntegrated Furnace Control \/ Ignition Control Module\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\u003eControl Voltage\u003c\/td\u003e\n\u003ctd\u003e24V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIgnition Type\u003c\/td\u003e\n\u003ctd\u003eHot Surface Ignition (HSI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eOEM replacement for the ICP Tempstar Heil WPG3364090LKC1 packaged gas\/electric unit and ICP-family furnaces (Heil, Tempstar, Comfortmaker) using this integrated control\/ignition module.
