ICP Furnace Control Board Kit for RGS213HSCA0AAAA — OEM Replacement | Ships Today

Overview

This OEM control board kit, part number 1183618, is the main integrated furnace control (IFC) for ICP-built gas furnaces. The control board is the brain of the furnace: it sequences the ignition cycle, energizes the inducer and gas valve, monitors safety limits and flame sensing, runs the blower on heat and cool calls, and reports diagnostic flash codes. Supplied as a kit, it includes the board and the hardware needed for a clean swap. A failed board causes no response to thermostat calls, blower or inducer that won't run, erratic short-cycling, or repeating fault flash codes. Always read the LED diagnostic code and confirm other components (igniter, flame sensor, limits) are good before condemning the board.
