It manages the heating sequence — inducer start, pressure-switch proof, igniter warm-up, gas valve timing, flame sensing, and blower on\/off delays — while coordinating the cooling call to the contactor. This listing covers the integrated circuit board (OEM 1178358) and its ignition control module (OEM 1177661), which together govern safe, timed ignition. When the board fails, the unit may lock out on ignition, fail to energize the igniter or gas valve, leave the blower running continuously, or show diagnostic LED fault codes. Boards commonly fail from power surges, moisture, corroded connectors, or burnt relays. Inspect the wiring harness and grounding before replacing, since a board failure is often a symptom of an upstream electrical fault.\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\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 \/ Ignition Control Board\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\u003e24 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLine Voltage\u003c\/td\u003e\n\u003ctd\u003e120 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit\u003c\/td\u003e\n\u003ctd\u003eOEM Replacement\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 ICP \/ Tempstar \/ Heil WPG3304040LKC1 packaged unit and related ICP-family equipment using this integrated control and ignition module.
