ICP Furnace Control Board for RGS213LRAA0AAAA — OEM Kit 1183618 | Ships Today

Overview

The OEM Control Board Kit (part #1183618) is the integrated furnace control (IFC) that manages ignition sequencing, blower and inducer timing, flame supervision, and safety lockouts on the ICP Tempstar Heil RGS213LRAA0AAAA gas furnace. A failed board commonly shows up as a furnace that won't ignite, a blower that runs nonstop or never starts, or a diagnostic LED flashing a fault code. This is the complete factory kit with the correct relays, microprocessor, and connectors to match the original equipment exactly, making it a reliable fix for intermittent no-heat calls.
