Overview
The ICP control board kit (OEM 1183618) is the integrated furnace control (IFC) that manages the entire heating sequence on the Tempstar/Heil RGS102SRCB0AAA gas furnace. It governs the ignition sequence, monitors the flame sensor and pressure switches, sequences the inducer and blower motors, and protects the system through safety lockouts. When this 24V board fails, the furnace typically will not start, locks out after a few ignition attempts, runs the blower continuously, or throws diagnostic flash codes on the LED. This is a complete OEM replacement kit supplied with the correct mounting hardware and wiring harness for a true plug-and-play swap.
