Overview
This OEM control board kit (part 1183618) is the brain of the ICP/Tempstar/Heil RGS150HFCA0AAAA package unit. It manages the entire heating sequence — inducer operation, hot surface igniter timing, gas valve control, flame sensing, blower on/off delays, and safety lockouts. The kit ships with the board and the mounting hardware needed for a complete replacement. When a control board fails you may see intermittent no-heat, the furnace stuck in lockout, blower running constantly, or no response at all to a thermostat call. Because the board ties every safety device together, a failed board should always be replaced with the correct OEM part rather than bypassed.
