Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP RGS102HSAA0AAA gas furnace. The integrated furnace control board is the brain of your heating system — it manages the ignition sequence, monitors safety circuits, sequences the inducer and blower motors, and coordinates the 24V control signals between the thermostat and the furnace components. When this board fails, the furnace may fail to ignite, short-cycle, lock out, or stop responding to the thermostat entirely. Common failure symptoms include a furnace that runs the inducer but never lights, a board with no diagnostic LED activity, scorched relay contacts, or visible cracking and burn marks on the circuit board. Replacing the board with the correct OEM kit restores reliable, code-compliant operation.
