ICP Furnace Control Board Kit for RGS213SREA0AAAA — Integrated Ignition | Ships Today

Overview

This genuine OEM control board kit (OEM part #1183618) is the integrated furnace control (IFC) brain for the ICP/Tempstar/Heil RGS213SREA0AAAA gas furnace. The board sequences the entire heating and cooling cycle — energizing the inducer, proving pressure, firing the igniter, opening the gas valve, monitoring the flame sensor, and timing the blower on and off delays. It also stores diagnostic fault codes via its LED. When the control board fails you may see the diagnostic LED dark or flashing a hard-fault code, no response to a thermostat call, the blower running continuously, or the furnace short-cycling. Supplied as a complete kit for a clean, OEM-spec replacement.
