Overview
This is a genuine OEM control board kit (part number 1183618) for the ICP / Tempstar / Heil RGS180HSAA0AAAA gas furnace. The integrated furnace control board is the brain of the furnace — it manages the ignition sequence, monitors safety limits and flame sense, sequences the inducer and blower motors, and controls the 24V signals to the gas valve. When this board fails the furnace may fail to ignite, lock out after a few attempts, run the blower continuously, or stop responding to the thermostat entirely. Replacing the board with the correct OEM kit restores reliable, code-compliant operation without guesswork.

Compatibility
Engineered as the factory replacement for the ICP Tempstar Heil RGS180HSAA0AAAA gas furnace. ICP-built furnaces share components across the Heil, Tempstar, Comfortmaker and Day & Night family, so always confirm the printed part number 1183618 against the board currently in your unit before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the furnace blower-compartment service panel to expose the control board.
- Document — Photograph every wire and connector position; label leads if needed so the new board matches exactly.
- Remove — Unplug each harness connector, remove the mounting screws/standoffs, and lift the old board out.
- Install — Mount the new 1183618 board, then reconnect every harness exactly per your photos.
- Test — Restore power and run a full heat cycle; confirm inducer, ignition, flame proof, and blower all sequence correctly.
Signs You Need a Replacement
- Furnace will not ignite or locks out after repeated trial-for-ignition attempts
- Blower runs continuously or never starts
