Overview
Genuine OEM control board kit, ICP part number 1183618, for ICP/Tempstar/Heil RGS-series gas furnaces. The integrated furnace control board is the brain of the unit — it manages the ignition sequence, blower and inducer timing, safety interlocks (limits, pressure switch, flame sensing), and diagnostic fault codes. When the board fails you may see no response to a call for heat, the blower or inducer running continuously or not at all, erratic cycling, or flashing diagnostic codes. This kit includes the replacement board so you can restore full furnace operation.
