ICP Furnace Control Board Kit for RGS180HFAA0AAAA — OEM Ignition Control 1183618 | Ships Today

Overview

This OEM control board kit (ICP part number 1183618, "KIT CONTROL BOARD") is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS180HFAA0AAAA gas furnace. It is the furnace's brain: it sequences the inducer, igniter, gas valve, and blower; monitors safety inputs such as the pressure switch and flame sensor; and manages ignition timing and lockout logic. Supplied as a complete kit so you have the board and any required mounting hardware for a clean replacement. A failed board causes no-heat calls, erratic blower behavior, or fault-code lockouts.
