ICP Furnace Control Board Kit for RGS244HSFA0AAAA — OEM 1183618 | Ships Today

Overview

This is the genuine OEM integrated furnace control board kit (part number 1183618) for the ICP Tempstar/Heil RGS244HSFA0AAAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, monitors safety limits and flame sense, sequences the inducer and blower motors, and times every heating cycle. When this board fails, the furnace typically stops responding entirely or locks out on repeated failed ignition attempts. This kit ships with the correct firmware and 24V control circuitry matched to your model.

Specifications

Compatibility

Engineered as a direct OEM replacement for the ICP Tempstar/Heil RGS244HSFA0AAAA. Always verify your existing board's part number and connector layout against 1183618 before installing. Many ICP-family gas furnaces share board platforms, but pin-out and firmware must match.

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 control/blower service panel.
3. Document — Photograph every wire and connector on the existing board before disconnecting anything.
4. Remove — Unplug the molex harnesses and 24V terminals, then unscrew the old board from its standoffs.
5. Install — Mount the new 1183618 board, reconnect each harness exactly per your photos, and set any dip switches to match the original.
6. Test — Restore power and run a full heat cycle, confirming inducer, ignition, flame sense, and blower all sequence correctly.

Signs You Need a Replacement

• Furnace completely unresponsive — no inducer, no ignition, no blower.
• Repeated ignition lockouts or rapid status-LED fault codes.
• Blower runs continuously or won't start.
• Visible burn marks, corrosion, or failed relays on the board.
