Overview
This OEM control board kit (part number 1183618, "KIT CONTROL BOARD") is the integrated furnace control for the ICP / Heil / Tempstar RGS180HDCA0AAAA gas furnace. The board manages the ignition sequence, blower and inducer timing, safety lockouts, and thermostat communication. When it fails, the furnace may not respond to a heat call, may short-cycle, may run the blower continuously, or may lock out with diagnostic LED fault codes. As a complete OEM kit it ships with the correct firmware/timings and mounting hardware so the sequence of operation matches the factory specification.
