Overview
This OEM control board kit (part #1183618) is the integrated furnace control (IFC) for the ICP/Heil/Tempstar RGS101STCA0AAA. It is the brain of the furnace — managing the ignition sequence, sequencing the inducer and blower, monitoring safety limits and flame sense, and driving the 24V control circuit. Power surges, age, and overheating are the usual causes of board failure, which can leave the furnace dead, stuck in lockout, or short-cycling. This kit ships with the components needed for a complete board swap.
