Overview
This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) brain of the ICP/Heil/Tempstar RGS243LDEA0AAAA gas furnace. It sequences the inducer, igniter, gas valve, and blower, manages safety interlocks, and reads the flame signal. A failed board causes complete no-heat, blower-only operation, the inducer never starting, or diagnostic LED fault codes that won't clear. Because the board ties every heating function together, replacing a faulty one restores reliable, code-compliant operation.
