ICP Furnace Control Board Kit for RGS213SFAA0AAAA — OEM | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the electronic brain of the ICP / Tempstar / Heil RGS213SFAA0AAAA gas furnace. The integrated furnace control manages the entire heating sequence: it reads the thermostat call, runs the inducer and pressure-switch safety check, energizes the igniter, opens the gas valve, proves flame, and stages the blower on and off. It also handles cooling and continuous-fan requests and stores diagnostic fault codes via an onboard LED. When a control board fails — often from surges, heat stress, or failed relays — the furnace may be completely dead, stuck in a fault code, short-cycling, or running the blower continuously. This complete kit ships with the matched board and mounting hardware for a clean OEM replacement.
