ICP Furnace Control Board for RGS101HRCA0AAA – Integrated Ignition Kit | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS101HRCA0AAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and flame sense, and communicates with the thermostat. It handles both 120V line voltage and 24V control signals. A failed board is a frequent cause of no-heat calls, intermittent operation, or a furnace that ignites then short-cycles. This is a complete kit for a direct OEM replacement.
