ICP Furnace Control Board Kit for RGS102LDCA0AAA — OEM Replacement | Ships Today

Overview

This OEM control board kit (PN 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS102LDCA0AAA gas furnace. The board is the brain of the system — it sequences the inducer, igniter, gas valve, and blower while monitoring the pressure switch, limit switch, and flame sensor for safe operation. When the board fails, you may see no response to a heat call, erratic blower behavior, repeated lockouts, or fault codes on the diagnostic LED. The kit ships with the mounting hardware and instructions needed for a direct factory replacement.
