ICP Control Board Kit for RGS210LFCA0AAAA — OEM 1183618 Furnace Control | Ships Today

Overview

This OEM Control Board Kit (part number 1183618) is the integrated furnace control board for the ICP/Tempstar/Heil RGS210LFCA0AAAA gas furnace. The board sequences the entire heating cycle — inducer, igniter timing, gas valve, flame sensing, and blower operation — while continuously monitoring pressure switches and safety limits. A failed board can cause no-heat conditions, short-cycling, repeated lockouts, or an unresponsive thermostat call. A diagnostic LED flashing a hard-fault code with no proper ignition sequence is a classic symptom. This kit ships complete and installs as a direct replacement.
