Overview
The ICP OEM Control Board Kit (part number 1183618) is the integrated furnace control module for the ICP / Tempstar / Heil model RGS180SFAA0AAAA gas furnace. This board manages the entire heating sequence — inducer startup, ignition timing, gas valve energizing, blower control, and safety lockouts. When the control board fails, the furnace may fail to ignite, short-cycle, run the blower continuously, or flash diagnostic fault codes. A failed board is one of the most common causes of a furnace that powers on but produces no heat. This is a complete OEM replacement kit supplied with the correct firmware and connector layout for your model, eliminating the guesswork of cross-referencing aftermarket boards.
