Overview
This OEM control board kit (P/N 1183618) is the integrated furnace control (IFC) brain of the ICP / Heil / Tempstar RGS120SEBA0AAA gas furnace. It manages the entire heating sequence: it reads the thermostat call, runs the inducer and pressure-switch proving, energizes the hot surface igniter, opens the gas valve, monitors flame via the flame sensor, and times the blower on and off delays. It also drives diagnostic LED fault codes that tell a technician exactly where a problem lies. When the board fails, the furnace may not respond to the thermostat, may lock out, may short-cycle, or may leave the blower running continuously. The kit ships with the board and the mounting/wiring hardware needed for a clean swap.
