Overview
This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS150LDCA0AAAA. The board is the brain of the furnace: it sequences the inducer, igniter, gas valve, and blower; monitors the flame sensor and pressure/limit switches; and manages safety lockouts and diagnostic fault codes. The kit ships with the mounting hardware and instructions needed for a complete swap. A failed board commonly presents as a dead furnace, blower that won't run, or a unit stuck in lockout despite good supporting components.
