Overview
This genuine OEM control board kit (part 1183618) for the ICP / Heil / Tempstar RGS102HTAA0AAA gas furnace is the integrated furnace control (IFC) that manages the entire heating sequence. It reads the thermostat call, sequences the inducer motor, energizes the hot surface igniter, opens the gas valve, monitors flame through the sensor, and times the blower on and off delays. The board also runs safety logic and flashes diagnostic fault codes via its LED. When the control board fails, the furnace may be completely dead, fail to start the inducer or igniter, short-cycle, or run the blower continuously. Supplied as a kit, it includes the correct board for a direct factory-matched replacement that restores full sequence control and safety monitoring.
