ICP Furnace Control Board Kit for RGS210SEAA0AAAA — OEM | Ships Today

Overview

This genuine OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS210SEAA0AAAA. The board is the brain of the furnace: it manages the ignition sequence, sequences the inducer and gas valve, energizes the hot surface igniter, controls blower on/off timing, and monitors the safety circuit including limits, pressure switches, and flame sensing. When the board fails you may see no response to thermostat calls, erratic blower behavior, repeated lockouts, or flashing diagnostic fault codes. Supplied as a kit with the hardware needed for a clean swap, this OEM board restores full sequencing and safety control.
