ICP Furnace Control Board Kit for RGS102LSCB0AAA — OEM Replacement | Ships Today

Overview

This OEM control board kit (P/N 1183618) for the ICP / Heil / Tempstar RGS102LSCB0AAA is the integrated furnace control (IFC) that orchestrates the entire heating sequence. It reads the thermostat, sequences the inducer, igniter, and gas valve, monitors the flame sensor and limit/pressure safeties, and times the blower on and off. When the board fails, symptoms range from a completely dead furnace to erratic blower operation, ignition lockouts, or short cycling. Supplied as a kit with the hardware needed for a clean swap, this board restores correct, code-compliant control of ignition, airflow, and safety timing.
