Overview
This is the genuine OEM furnace control board kit (OEM 1183618) for the ICP Tempstar Heil RGS102HDBB0AAA gas furnace. The integrated furnace control board is the brain of the unit — it sequences the ignition cycle, energizes the inducer and hot surface igniter, opens the gas valve, manages blower-on and blower-off timing, and monitors the safety circuit (limit switches, pressure switch, flame sense). When the board fails, the furnace may not respond to a heat call at all, may lock out intermittently, may run the blower continuously, or may behave erratically as solder joints and relays degrade with age and heat. Supplied as a complete kit, this OEM board restores correct, code-compliant operation and the proper diagnostic LED fault codes.
