ICP Furnace Control Board Kit for RGS210STAA0AAAA | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) for ICP, Tempstar, and Heil gas furnaces is the integrated furnace control that manages the entire heating sequence — igniter timing, gas valve operation, inducer and blower relays, safety limit monitoring, and self-diagnostic fault codes. The board is the brain of the furnace; when it fails the unit may show no response on a heat call, ignite erratically, leave the blower running continuously, or flash error codes. The kit includes the replacement board and mounting hardware for a complete swap. Installing a fresh control board restores proper ignition sequencing, blower control, and safety interlocks.
