ICP Furnace Control Board Kit for RGS180SSEA0AAAA — OEM Replacement | Ships Today

Overview

This is a genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS180SSEA0AAAA gas furnace. The integrated furnace control board is the brain of the furnace — it sequences ignition, manages the inducer and blower motors, monitors safety limits and flame, and communicates with the thermostat. When the board fails, you may see no response to a call for heat, blower or inducer motors that won't run, or fault codes flashing on the diagnostic LED. This kit ships with the mounting hardware and instructions needed for a complete OEM-spec replacement.

Specifications

Compatibility

Built as a direct OEM replacement for the ICP / Tempstar / Heil model RGS180SSEA0AAAA. The same control kit services many matched Comfortmaker, Arcoaire, and KeepRite furnaces on the shared ICP platform. Confirm the board's connector layout and harness pinout against your existing control before installing.

Installation Guide

1. Safety First — Disconnect electrical power and gas; verify zero voltage with a multimeter before touching the board.
2. Access — Remove the furnace blower/control compartment door.
3. Document — Photograph every wire harness and plug location on the old board before disconnecting.
4. Remove — Unplug each harness, release the board from its standoffs, and lift it out.
5. Install — Mount the new board with the supplied hardware and reconnect every harness exactly as photographed.
6. Test — Restore power and gas, run a full heat cycle, and confirm the diagnostic LED shows normal operation with no fault codes.

Signs You Need a Replacement

• No response from the furnace on a call for heat
• Inducer or blower motor won't energize
