ICP Furnace Control Board Kit for RGS091HECA0AAA — OEM 1183618 | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS091HECA0AAA gas furnace. The board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and the flame sensor, and times each stage of the heating cycle. When the board fails, the furnace may not respond to the thermostat, fail to ignite, short-cycle, or run the blower continuously. Supplied as a complete kit with the hardware and instructions needed for a direct, factory-spec replacement.

Compatibility

Direct OEM replacement for the ICP/Tempstar/Heil RGS091HECA0AAA gas furnace and related RGS091 models that specify control board kit 1183618. Because control board part numbers are revision-specific, confirm 1183618 against your furnace's rating plate or parts diagram before ordering.
