ICP Furnace Control Board Kit for RGS102HECA0AAA — OEM Module | Ships Today

Overview

This genuine OEM control board kit (part 1183618) for the ICP / Tempstar / Heil RGS102HECA0AAA is the integrated furnace control that sequences the entire heating cycle. It manages the inducer, igniter, gas valve, and blower timing, monitors the limit and pressure switches, reads the flame sensor, and runs the diagnostic LED fault codes. A failed control board causes no-heat, no-blower, short cycling, or repeated lockouts that no single component swap resolves. The kit ships with the mounting hardware and instructions needed for a clean drop-in replacement so the furnace returns to safe, fully sequenced operation.
