ICP Furnace Control Board Kit for RGS210HFCA0AAAA — Integrated Control | Ships Today

Overview

Genuine OEM control board kit (ICP part 1183618) for the ICP/Tempstar/Heil RGS210HFCA0AAAA furnace. The integrated furnace control board is the brain of the unit — it manages the ignition sequence, sequences the inducer and blower motors, monitors safety circuits (limits, pressure switch, flame sense), and times each stage of the heat cycle. When the board fails, symptoms range from no response on a call for heat to erratic blower behavior, repeated lockouts, or fault codes flashed on the diagnostic LED. This kit includes the replacement board for a direct swap.

4. Remove — Unplug each connector, release the board standoffs/screws, and lift the old board out.
