ICP Furnace Control Board Kit for RGS210HTAA0AAAA — OEM | Ships Today

Overview

This is the genuine OEM control board kit (OEM part 1183618) for the ICP / Tempstar / Heil RGS210HTAA0AAAA packaged gas/electric unit. The integrated control board is the brain of the unit — it manages the ignition sequence, sequences the inducer and blower, monitors safety limits and the flame signal, and switches the cooling outputs. The kit ships with the board and the mounting/wiring components needed for a clean replacement. When the board fails you typically see no response to a thermostat call, blower or inducer that won't run, ignition lockouts, or fault codes flashing on the diagnostic LED. Because it controls every sequence, a failed board can mimic many other component failures, so confirm the board with diagnostics before replacing.
