Overview
The OEM Control Board Kit (part number 1183618) is the integrated furnace control module for the ICP Tempstar Heil RGS180HTEA0AAAA gas furnace. This board manages the ignition sequence, blower and inducer timing, safety lockouts, and communication between the thermostat and the furnace's electrical components. When the control board fails, the furnace may fail to ignite, short-cycle, run the blower continuously, or display fault codes on the diagnostic LED. This kit ships complete with the board and the required mounting hardware so you can perform a clean drop-in replacement. The board operates on a 24V control circuit and is matched to the RGS180 furnace platform.
