Overview
This OEM control board kit (OEM #1183618) is the brain of your ICP / Tempstar / Heil RGS150LRCB0AAAA furnace. It manages the entire heating sequence — inducer startup, igniter timing, gas valve operation, flame sensing, and blower control — while monitoring safety limits and pressure switches. When the board fails, the furnace may not respond to the thermostat, may flash diagnostic fault codes, may run the blower continuously, or may fail to advance through the ignition sequence at all.
