ICP Control Board Kit for RGS180HDEA0AAAA — OEM Furnace Control | Ships Today

Overview

The 1183618 Control Board Kit is the OEM integrated furnace control (IFC) for the ICP Tempstar/Heil RGS180HDEA0AAAA gas furnace. This board manages the complete heating sequence — igniter timing, gas valve activation, inducer and blower motor operation, flame sensing, and safety lockouts. When it fails, the furnace will not fire, cycles erratically, or locks out on diagnostic fault codes. Replacing it with the exact OEM kit restores proper sequencing and preserves any safety interlocks that aftermarket boards may not match.

4. Remove — Unplug the molex harnesses, release the board standoffs/screws, and lift out the failed board.
