ICP Control Board Kit for RGS243SEEA0AAAA — Furnace Ignition | Ships Today

Overview

This OEM control board kit (part #1183618) is the brain of your ICP/Tempstar/Heil RGS243SEEA0AAAA gas furnace. The integrated furnace control sequences every heat cycle: it proves the pressure switch, runs the inducer, energizes the igniter, opens the gas valve, monitors flame, and times the blower on and off. It also manages safety lockouts and stores diagnostic fault codes via its onboard LED. Boards fail from voltage surges, overheating, cracked solder joints, and failed relays — leaving you with no heat, a blower that won't start or won't stop, or flashing error codes. This kit ships with the mounting hardware and connectors needed for a clean OEM replacement, restoring correct ignition timing and safety operation.
