ICP Furnace Control Board Kit for RGS102HEAB0AAA — OEM Replacement | Ships Today

Overview

This OEM control board kit (part number 1183618) is the brain of your ICP Tempstar Heil RGS102HEAB0AAA gas furnace. It sequences the entire heat cycle — proving the pressure switch, energizing the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower on/off delays. It also handles 24V thermostat inputs and safety lockouts. When a board fails you may see no response to a heat call, erratic blower behavior, or repeated lockouts. Many ICP control boards include a diagnostic LED that flashes fault codes; a board that won't power up or won't clear faults needs replacement.
