This OEM Control Board Kit (part number 1183618) is the integrated ignition and circuit-control board that manages the heating and blower sequence in your ICP / Tempstar / Heil RGS150SEBA0AAAA gas-electric package unit. The board orchestrates the entire cycle: it processes the thermostat call, runs the inducer and pressure-switch proving, energizes the hot surface igniter, opens the gas valve, monitors flame, and times the blower on/off delays. A failed control board produces erratic or no-heat behavior, ignition lockouts, blower problems, or a completely dead system. Supplied as a complete kit with mounting hardware and instructions, this OEM board restores correct, safe ignition sequencing and full diagnostic LED functionality.
