ICP Furnace Control Board Kit for RGS102HECB0AAA — OEM 1183618 | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS102HECB0AAA gas furnace. The board is the brain of the furnace: it sequences the inducer, igniter, gas valve, and blower, monitors the pressure switch and flame sensor for safety, and runs self-diagnostics with a fault-code LED. When the board fails, you see intermittent no-heat calls, blower or inducer that won't start or won't stop, scrambled or blank diagnostic codes, or repeated lockouts even after good igniter and sensor parts are installed. The kit includes the board and mounting hardware for a complete replacement.
