The integrated furnace control board is the brain of the appliance — it sequences the inducer, igniter, gas valve, and blower, monitors the flame sensor and pressure switch safeties, and flashes diagnostic fault codes. When the board fails, the entire furnace goes down. Common failure symptoms include a completely dead furnace with no response to a heat call, a thermostat that powers up but the unit never sequences, no blower or inducer operation, erratic or random short cycling, and diagnostic LEDs that are dark or stuck on an error code. Boards commonly fail from power surges, a failed transformer, condensate or rodent damage, or burnt relays and cracked solder joints. This kit ships with the mounting hardware and instructions needed for a clean swap.\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\u003e1183618\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eIntegrated Furnace Control Board Kit\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\u003eIgnition Sequencing \u0026amp; Safety Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncludes\u003c\/td\u003e\n\u003ctd\u003eControl Board + Mounting Hardware\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\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\u003eExact OEM-fit kit for the ICP RGS120HTAB0AAA and the matching Tempstar, Heil, and Comfortmaker furnaces built on the same chassis.
