ICP Control Board Kit for RGS240HEFA0AAAA — OEM Furnace Board | Ships Today

Overview

This genuine OEM control board kit (part 1183618) fits the ICP/Heil/Tempstar RGS240HEFA0AAAA gas furnace. The integrated furnace control board is the brain of the system — it manages the ignition sequence, inducer and blower timing, safety lockouts, and communication between the thermostat, igniter, gas valve, and limit switches. When the board fails, symptoms range from no response on a call for heat, to a furnace that ignites but never starts the blower, to repeated lockouts and flashing diagnostic codes. The kit includes the OEM board and required hardware for a direct replacement.
