ICP Furnace Control Board Kit for RGS214LRAA0AAAA | Ships Today

Overview

This is a genuine OEM control board kit (OEM part #1183618) for the ICP / Tempstar / Heil RGS214LRAA0AAAA gas furnace. The integrated furnace control board is the brain of the system: it sequences the ignition cycle, energizes the inducer motor, fires the igniter, opens the gas valve, runs the blower at the correct heat and cool speeds, and continuously monitors the safety circuit (pressure switch, limit switch, flame sense). When the board fails, the entire furnace can become unresponsive or behave erratically — short cycling, no inducer start, blower running constantly, or flashing diagnostic fault codes. This kit ships with the components needed for a direct OEM replacement.
