ICP Integrated Furnace Control Board for RGS150SFBA0AAAA — Ignition Control | Ships Today

Overview

This is the genuine OEM integrated furnace control board kit for the ICP / Heil / Tempstar RGS150SFBA0AAAA gas furnace, OEM part number 1183618. The control board is the brain of the furnace: it manages the ignition sequence, sequences the inducer and gas valve, energizes the 120V hot surface igniter, controls the blower (heat and fan), monitors safety limits and flame sense, and flashes diagnostic fault codes via its onboard LED. When the board fails, the furnace may be completely dead, stuck on continuous blower, fail to ignite, or short-cycle on false faults.

Installation Guide

1. Safety First — Disconnect power at the switch and breaker, and verify zero voltage with a multimeter.
2. Access — Remove the furnace blower-compartment service panel.
3. Document — Photograph every wire and connector on the old board, or transfer one wire at a time.
4. Remove — Unplug all harness connectors and low-voltage leads, remove the mounting screws, and lift out the failed board.
5. Install — Mount the new board, set any DIP switches / timing jumpers to match the original, and reconnect every wire per your photo.
6. Test — Restore power, run a full heat and fan cycle, and confirm there are no fault-code flashes.

Signs You Need a Replacement
