It manages the entire heating sequence — inducer startup, hot surface igniter timing, gas valve operation, flame sensing, and blower control — while monitoring the limit and pressure safety switches. Supplied as a complete kit with the correct connectors and instructions, it replaces a board that has failed due to surges, corrosion, or burned relays. A bad board often shows as a dead unit, an inducer or igniter that won't sequence, or repeated lockouts with no obvious component 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\u003eOEM Part Number\u003c\/td\u003e\n\u003ctd\u003e1183618 (Kit, Control Board)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eIntegrated Furnace Control Board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eICP (Tempstar \/ Heil \/ Comfortmaker)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLine Voltage\u003c\/td\u003e\n\u003ctd\u003e120V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctions\u003c\/td\u003e\n\u003ctd\u003eIgnition, blower, gas valve, flame sense, safety sequencing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eFits the ICP \/ Tempstar \/ Heil RGS240HFFA0AAAA rooftop gas-electric package unit and related RGS240-series cabinets that use this integrated control kit.
