ICP Furnace Control Board Kit for RGS210SSEA0AAAA — OEM Replacement | Ships Today

Overview

This is a genuine OEM control board kit, part number 1183618, for the ICP, Tempstar, and Heil RGS210SSEA0AAAA gas furnace. The integrated furnace control board is the brain of the system: it manages the ignition sequence, sequences the inducer, igniter, gas valve, and blower, monitors safety inputs such as pressure switches and limit switches, reads flame sense, and runs self-diagnostics via an LED fault code. A failed board can cause no-heat, erratic operation, blower or inducer problems, repeated lockouts, or a furnace that ignores the thermostat entirely. The kit includes the board needed for a direct OEM replacement.
