Overview
This is the genuine OEM Control Board Kit (part number 1183618) for the ICP Tempstar Heil RGS150LFCB0AAAA gas furnace. The integrated furnace control board is the brain of the unit — it manages the ignition sequence, sequences the inducer and blower motors, monitors safety interlocks (limit switches, pressure switch, flame sense), and runs the diagnostic LED. When the board fails, the furnace may not respond to the thermostat, blower or inducer may not run, the unit may lock out, or the diagnostic LED may flash a fault or go dark. This OEM kit is the correct factory replacement with matching connectors and pre-programmed timings, so no reconfiguration is required.

Compatibility
Built for the ICP Tempstar Heil RGS150LFCB0AAAA gas furnace and other units specifying control board kit 1183618. Always confirm your model and serial tag and the original board part number, as control boards are model-specific and not interchangeable across series.
Installation Guide
- Safety First — Disconnect power and shut off gas. Verify zero voltage with a multimeter before handling the board.
- Access — Remove the furnace door/blower panel to expose the control board.
- Document — Photograph every connector, wire color, and terminal position before unplugging anything.
- Remove — Unplug all harness connectors, remove the mounting screws, and lift out the old board.
- Install — Mount the new board, reconnect every harness to its matching connector per your photo, and confirm all plugs are fully seated.
- Test — Restore power and gas, run a full heat cycle, and verify ignition, blower operation, and a normal diagnostic LED with no fault codes.
