ICP Control Board Kit for RGS180SEAA0AAAA — OEM Furnace Board | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS180SEAA0AAAA. The board is the brain of the furnace: it sequences ignition, runs the inducer and blower, monitors safety limits and flame, and manages timing on every heat call. The kit ships with the board and the hardware needed to swap it. When a control board fails — usually from heat stress, surface-mount relay failure, or a power surge — the furnace can lock out, short-cycle, or refuse to fire entirely. A fresh OEM board restores full, code-compliant sequencing.
