ICP Furnace Control Board Kit for RGS210LREA0AAAA — OEM | Ships Today

Overview

This genuine OEM control board kit (OEM 1183618) is the brain of the ICP / Tempstar / Heil RGS210LREA0AAAA packaged unit. The integrated ignition control board sequences the entire heat cycle — proving the pressure switch, energizing the inducer and igniter, opening the gas valve, monitoring flame, and timing the blower on and off delays. It also manages safety lockouts and self-diagnostic fault codes. When a board fails from a power surge, failed relay, or cracked solder joint, the unit may go completely dead, fail to ignite, or short-cycle. This kit includes the mounting hardware and instructions for a complete replacement.
