ICP Furnace Control Board Kit for RGS180STEA0AAAA — OEM 1183618 | Ships Today

Overview

This is the genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS180STEA0AAAA gas furnace. The integrated furnace control board is the brain of the system: it manages the ignition sequence, monitors safety limits and the flame sensor, sequences the inducer and blower motors, and communicates with the thermostat. A failed board causes some of the most common no-heat calls — no response to the thermostat, no inducer or blower operation, ignition lockouts, or erratic cycling. This factory kit includes the correct board and the hardware needed for a clean, direct replacement.

Installation Guide

3. Document — Photograph every connector and wire location; note the position of any DIP switches or jumpers.
4. Remove — Unplug all harness connectors, unfasten the board standoffs/screws, and lift out the old board.
5. Install — Mount the new board, set switches/jumpers to match the original, and reconnect every harness per your photos.
