ICP Furnace Control Board Kit for RGS101SRCA0AAA — OEM Replacement | Ships Today

Overview

This OEM control board kit (part number 1183618) is the integrated furnace control module for the ICP RGS101SRCA0AAA. It manages the entire heating sequence — inducer startup, igniter warm-up, gas valve timing, flame sensing, and blower control — and monitors safety limits and pressure switches. Control boards fail from voltage surges, corroded or burned relays, cracked solder joints, or blown onboard fuses. A failed board can leave the furnace completely dead, stuck in lockout, or short-cycling, and is often signaled by a diagnostic LED fault code.
