ICP Furnace Control Board Kit for RGS180LRCA0AAAA — OEM Part 1183618 | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) that runs the entire ignition and safety sequence on the ICP / Tempstar / Heil RGS180LRCA0AAAA gas furnace. It manages the inducer, igniter, gas valve, and blower timing, monitors the flame sensor and safety limits, and flashes diagnostic fault codes through its onboard LED. When the board fails, the furnace may be completely dead, stuck on continuous blower, locked out on ignition, or throwing erratic fault codes. The kit ships with the matched board and mounting hardware for a direct factory replacement.
