This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS213LDEA0AAAA package unit. The control board is the brain of the system: it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and pressure switches, reads the flame signal, and coordinates heating and cooling calls from the thermostat. Because it ships as a complete kit, it includes the components needed for a clean replacement. A failed board can cause no heat, no blower, an inducer that won't start, blown fuses, or erratic operation and diagnostic fault codes on the board's LED.
