Overview
This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) that runs the ICP RGS150LECB0AAAA gas furnace. The board is the brain of the system: it sequences ignition, monitors the flame sensor and limit switches, controls the inducer and blower motors, manages timing and safety lockouts, and communicates with the thermostat. Control boards fail from voltage surges, heat stress, corrosion, and cracked solder joints, producing symptoms ranging from intermittent no-heat to a completely dead furnace. Supplied as a kit with the hardware needed for a clean swap, this board restores full furnace operation and built-in safety logic.
