Overview
This genuine ICP control board kit (OEM #1183618) is the integrated furnace control (IFC) board for the RGS244HDAA0AAAA gas furnace. It is the brain of the unit, sequencing the inducer motor, hot surface igniter, gas valve, and blower while monitoring safety limits and flame signal. A failed board is one of the most common causes of a furnace that will not start, short cycles, or locks out. Symptoms of failure include no response on a call for heat, blower running continuously, error codes on the diagnostic LED, or intermittent ignition. The kit ships with mounting hardware and the wiring harness connections needed for a direct replacement.
