Overview
This OEM control board kit (OEM 1183618) is the integrated furnace control (IFC) — the brain of the ICP/Tempstar/Heil RGS102SRCA0AAA gas furnace. It manages the entire heat sequence: it reads the thermostat call, runs the inducer and pressure-switch proving, energizes the hot surface igniter, opens the gas valve, monitors flame via the sensor, and stages the blower on and off. It also handles safety lockouts and flashes diagnostic fault codes via its onboard LED. A failed board produces intermittent no-heat, short cycling, or a completely dead furnace. This is a complete factory kit with the mounting hardware needed for a direct swap.

Installation Guide
- Safety First — Disconnect power at the switch and breaker. Verify zero voltage with a multimeter before touching the board.
- Access — Remove the blower compartment service panel to expose the control board.
- Document — Photograph every wire and connector position; many terminals look alike.
- Remove — Label and disconnect the harnesses, remove the mounting screws/standoffs, and lift out the old board.
- Install — Mount the new board, transfer the wiring exactly per your photos, and set any jumpers/dip switches to match the originals.
- Test — Restore power, run a full heat cycle, and confirm a steady diagnostic LED with proper igniter, gas valve, and blower sequencing.
Signs You Need a Replacement
- Furnace is completely dead with no diagnostic LED.
- Igniter, inducer, or blower fails to energize in sequence.
