Overview
This is the genuine OEM Integrated Furnace Control (IFC) board kit, part number 1183618, for the ICP/Tempstar/Heil RGS102LRCB0AAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower motors, monitors the flame sensor and pressure switch, and controls the 24V signals to the gas valve. The kit ships complete with mounting hardware so it drops straight into the existing board location. When this board fails, the most common symptoms are a furnace that will not start, an inducer that runs but no ignition, a blower that never shuts off, or repeated fault-code lockouts on the diagnostic LED.
