Overview
This OEM control board kit (part #1183618) is the integrated furnace control (IFC) brain of the ICP / Tempstar / Heil RGS150HTCB0AAAA gas furnace. It sequences the ignition, manages the inducer and blower relays, monitors the flame sensor and limit/pressure switches, and communicates fault codes via its diagnostic LED. A failed board produces erratic behavior — no ignition, blower that won't start or won't stop, short-cycling, or a dead furnace with no LED. Heat, moisture, power surges, and aged relays are common causes of board failure. This factory kit includes the board and mounting hardware for a clean, code-correct replacement.
