ICP Furnace Control Board Kit for RGS210SFCA0AAAA — OEM Replacement | Ships Today

Overview

This genuine OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP Tempstar/Heil RGS210SFCA0AAAA gas/electric package unit. The board is the brain of the system: it sequences ignition, runs the inducer and blower, monitors flame and limit/pressure safeties, and manages timing for heating and cooling. A failed board produces a wide range of symptoms — no response on a call, blower that won't start or won't shut off, ignition lockouts, or erratic LED fault codes. The kit ships with the replacement board and the mounting hardware needed for a clean swap, restoring proper safety supervision and operating sequence to the unit.
