ICP Furnace Control Board Kit for RGS210LSEA0AAAA — OEM Part 1183618 | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS210LSEA0AAAA gas furnace. The board is the brain of the furnace — it manages the ignition sequence, blower and inducer timing, safety interlocks, and thermostat communication. When the board fails, the furnace may not respond to a heat call, the blower or inducer may run continuously or not at all, or you may see error codes flashed on the diagnostic LED. The kit ships with the mounting hardware and instructions needed for a complete swap.
