Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP/Heil/Tempstar RGS102HFCB0AAA 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 flame sensing, and communicates with the thermostat over the 24-volt control circuit. It also drives the hot surface igniter and gas valve in the correct order on every heat cycle. When the board fails, the furnace may be completely dead, short-cycle, lock out on flame-sense faults, or run the blower continuously. Most boards include diagnostic LED fault codes to speed troubleshooting. The kit ships with the mounting hardware needed for a clean swap.
