ICP Furnace Control Board Kit for RGS180SSAA0AAAA — OEM Part 1183618 | Ships Today

Overview

This is the OEM control board kit (part number 1183618) for the ICP/Heil/Tempstar RGS180SSAA0AAAA gas furnace. The integrated furnace control board is the brain of the unit — it sequences the inducer, igniter, gas valve, and blower, monitors limit and pressure switches, proves flame, and runs the safety lockouts. The kit ships as a complete assembly so you replace the board with the correct firmware and connector layout for this model. A failed board shows up as no response to a heat call, blower or inducer that won't run, flashing diagnostic LED fault codes, or random lockouts. This direct-fit OEM kit restores full sequence-of-operation control.
