Overview
This genuine OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS102LDCB0AAA gas furnace. The board manages the entire heating sequence — inducer operation, igniter timing, gas valve sequencing, blower on/off delays — and monitors the limit, pressure, and flame safety circuits. A failed control board produces erratic behavior: no ignition, blower that won't start or won't stop, repeated lockouts, or a unit that's completely dead. Replacing the board restores correct, safe sequencing.
