Overview
This is the genuine OEM furnace control board kit (part number 1183618) for the ICP Tempstar Heil RGS180LDAA0AAAA gas furnace. The integrated control board is the brain of the furnace: it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and flame sense, and communicates with the thermostat. The kit includes the board and the hardware needed for a clean replacement. When the board fails, the furnace may show no response to a heat call, fail to ignite, short-cycle, lock out, or run the blower continuously. Diagnostic LED fault codes that won't clear after sensor and igniter checks often point to the board. This OEM kit restores full, factory-correct control operation.
