Overview
This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP Tempstar Heil RGS091SRCA0AAA. The board is the brain of the furnace: it sequences the entire heat cycle — energizing the inducer, proving pressure switches, powering the hot surface igniter, opening the gas valve, monitoring flame via the sensor, and timing the blower on and off. It also manages cooling and continuous-fan modes and stores diagnostic fault codes on its LED. Control boards fail from voltage surges, cracked solder joints, burned relays, and corroded connectors, producing symptoms that range from no operation to erratic cycling. The kit includes the board with the correct firmware and connectors for a direct factory replacement.

Compatibility
Direct OEM control board for the ICP/Tempstar/Heil RGS091SRCA0AAA furnace. ICP uses common integrated furnace controls across its Tempstar, Heil, Comfortmaker, and Arcoaire branded furnaces, so this kit may also service related models. Match the board's part number, connector layout, and terminal positions to your existing control before installing.
Installation Guide
- Safety First — Disconnect furnace power and verify zero voltage with a multimeter.
- Access — Remove the blower/control compartment service panel to expose the board.
- Document — Photograph every connector, plug, and terminal — this is critical for a control board swap.
- Remove — Unplug all wiring harnesses and low-voltage terminals, remove the mounting screws, and lift out the old board.
- Install — Mount the new 1183618 board and reconnect each harness and wire to the identical position per your photos.
- Test — Restore power, run a heat and a cool call, and confirm correct ignition, blower timing, and a normal status LED with no fault codes.
Signs You Need a Replacement
- Furnace completely dead with no LED activity
- Blower or inducer that won't start or won't stop
- Hard-flashing or no-flash diagnostic LED indicating board fault
- Random short-cycling, no ignition, or burned/scorched spots on the board
