ICP Furnace Control Board Kit for RGS213SRCA0AAAA | Ships Today

Overview

This OEM control board kit (part #1183618) is the integrated furnace control (IFC) — the brain of your ICP/Tempstar/Heil RGS213SRCA0AAAA furnace. It manages the ignition sequence, blower and inducer timing, safety interlocks (limit switch, pressure switch, flame sensing), and the thermostat interface. When the board fails, the furnace can show erratic behavior: no response to the thermostat, blower or inducer that won't start or won't stop, ignition lockouts with no obvious cause, or a flashing diagnostic LED fault code. Shipped as a kit with the necessary mounting hardware and instructions.
