Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS180SFCA0AAAA gas furnace. The integrated furnace control board is the brain of the system: it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and pressure switches, and times every heat and cool cycle. Supplied as a complete kit with the required mounting hardware and connectors, it replaces a board that has failed from power surges, heat stress, cracked solder joints, or relay wear. Typical failure symptoms include no ignition, blower or inducer that will not run, error/flash codes, or a furnace that is completely unresponsive.
