ICP Furnace Control Board Kit for RGS091HECB0AAA — OEM 1183618 | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS091HECB0AAA. The board is the brain of the furnace: it manages the ignition sequence, sequences the inducer and blower, monitors the flame sensor and pressure/limit safeties, and stores diagnostic fault codes on its LED. Control boards fail from voltage surges, cracked solder joints, burned relays, and heat or moisture damage. Symptoms include a dead furnace, no ignition sequence, blower or inducer that won't run, or flashing error codes. This kit is supplied as a genuine OEM assembly for a reliable, code-correct repair.
