Overview
This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for your ICP / Heil / Tempstar RGS102LSBB0AAA gas furnace. It governs the entire heating sequence — inducer start, pressure switch proving, igniter warm-up, gas valve timing, flame sensing, and blower on/off delays — while monitoring safety limits. A failed board is one of the most common no-heat causes: cracked solder joints, blown relays, or a tripped onboard fuse will halt operation or cause erratic cycling. The board operates on 120V line input with a 24V control circuit.
