ICP Furnace Control Board Kit for RGS213SFCA0AAAA — 24V | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control for the ICP/Tempstar/Heil RGS213SFCA0AAAA gas furnace. The board is the brain of the system — it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and flame sense, and drives the 24V control circuit. A failed board commonly causes a furnace that will not start, no inducer or blower operation, blinking diagnostic LED fault codes, or random lockouts. Supplied as a complete kit with the components needed for a clean factory replacement.

Built as the factory replacement control for the ICP RGS213SFCA0AAAA and related Tempstar, Heil, and Comfortmaker furnaces that use this integrated control platform. Match the printed part number on your existing board before ordering, as control boards vary by furnace series.
