ICP Furnace Control Board Kit for RGS180LTEA0AAAA — OEM Ignition Control | Ships Today

Overview

This genuine OEM furnace control board kit (Part #1183618) is the integrated ignition control ("brain") for the ICP / Tempstar / Heil RGS180LTEA0AAAA gas furnace. The board sequences the entire heating cycle: it runs the inducer, proves the pressure switch, energizes the igniter, opens the gas valve, monitors flame, and times the blower on and off. It also manages safety lockouts and flashes diagnostic fault codes. A failed board commonly causes a dead furnace, no inducer or blower operation, repeated lockouts, or erratic cycling. The kit includes mounting hardware for a complete, straightforward replacement.
