Overview
This OEM Control Board Kit (Part Number 1183618) is the integrated furnace control (IFC) that manages the entire heating sequence in your ICP / Tempstar / Heil RGS240LFAA0AAAA furnace. It governs the inducer, igniter, gas valve, and blower timing, monitors safety circuits, and reads the thermostat call. Supplied as a complete kit with the correct firmware and connectors for the RGS240 platform, it replaces a board that fails from heat stress, voltage surges, or burned relays. A failing board produces no-heat calls, erratic blower behavior, or flashing diagnostic fault codes. This factory kit restores correct, safe sequencing.
