Overview
This OEM control board kit (Part No. 1183618) is the electronic brain of your ICP RGS210LRCA0AAAA system. It manages the ignition sequence, blower and inducer timing, safety lockouts, and communication between the thermostat and the unit's components. The kit includes the board and necessary mounting hardware for a complete replacement. Control boards fail from power surges, heat stress, corroded relays, or cracked solder joints — symptoms include a dead unit, blinking diagnostic LED fault codes, blowers or igniters that won't sequence, or erratic operation. Replacing a failed board with a genuine OEM kit restores full diagnostic and safety functionality.
