ICP Furnace Control Board Kit for RGS102SRBA0AAA — OEM 1183618 | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) brain of the ICP / Tempstar / Heil RGS102SRBA0AAA. It sequences the entire heating cycle — inducer start, pressure switch proving, igniter warm-up, gas valve timing, flame sensing, and blower on/off delays — and provides the safety lockouts that protect the system. Boards fail from voltage surges, cracked solder joints, blown onboard fuses, and burned relays, producing symptoms ranging from no ignition to a blower that never starts or never stops. Supplied as a kit for a direct OEM replacement that restores correct timing and safety logic.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
2. Access — Remove the blower-compartment service panel to reach the control board.
3. Document — Photograph every connector and the wiring diagram label before unplugging anything.
4. Remove — Unplug the harness connectors, remove the mounting screws, and lift out the failed board.
5. Install — Mount the new board, set any DIP switches/jumpers to match the original, and reconnect each plug per your photos.
6. Test — Restore power, run a full heat cycle, and verify inducer, ignition, gas valve, flame sense, and blower all sequence correctly.

Signs You Need a Replacement

• No response on a heat call — inducer and igniter stay dead
• Blower runs constantly or never engages
• Repeated lockouts with diagnostic LED fault codes
• Visible burn marks, blown fuse, or scorched relays on the board
