ICP Control Board Kit for RGS244HSAA0AAAA — OEM Integrated Furnace Control 1183618 | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS244HSAA0AAAA gas furnace. The board is the brain of the appliance — it manages the ignition sequence, blower and inducer timing, safety lockouts, and 24V signaling between the thermostat, gas valve, igniter, and limit switches. When a control board fails, the furnace may fail to ignite, short-cycle, run the blower continuously, or flash a diagnostic fault code on the onboard LED. Replacing the board with the exact OEM kit restores factory timing and protects downstream components.

Specifications

Compatibility

Designed as a direct OEM replacement for the ICP Tempstar Heil RGS244HSAA0AAAA furnace and related RGS-series models that originally shipped with control 1183618. Always verify the printed part number on your existing board before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the furnace blower-compartment service panel.
3. Document — Photograph every wire and connector position on the existing board before disconnecting.
4. Remove — Unplug the wiring harnesses, release the board mounting standoffs/screws, and lift out the old control.
5. Install — Seat the new board on the standoffs and reconnect each harness exactly per your photos.
6. Test — Restore power, initiate a heat call, and confirm proper ignition, blower, and inducer operation with no fault codes.

Signs You Need a Replacement
