Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP/Heil/Tempstar RGS150SFCB0AAAA gas furnace. The integrated furnace control board is the brain of the system: it sequences the ignition cycle, controls the inducer and blower motors, monitors safety devices such as limit and flame sensors, and manages the 24V thermostat call. When the board fails, symptoms range from no response on a heat call, to blower or inducer that won't run, to error codes flashed on the diagnostic LED. Power surges, moisture, and aging relays are common causes of board failure.

Compatibility
Supplied as the factory replacement kit for the ICP RGS150SFCB0AAAA and shared across compatible ICP-family (Heil, Tempstar, Comfortmaker) furnaces. Because control boards are revision-specific, match the kit part number and verify the connector layout against your existing board before installing.
Installation Guide
- Safety First — Disconnect electrical power and verify zero voltage with a multimeter before touching the board.
- Access — Remove the control-compartment service panel.
- Document — Photograph every connector and the position of any DIP switches or jumpers before disconnecting.
- Remove — Unplug all wire harnesses, release the board standoffs/screws, and lift out the old board.
- Install — Mount the new board, transfer DIP-switch/jumper settings to match the original, and reconnect each harness exactly as photographed.
- Test — Restore power, run a full heat cycle, and confirm ignition, blower, and diagnostics operate normally with no fault codes.
Signs You Need a Replacement
- No response from the furnace on a thermostat heat call.
- Blower or inducer motor will not start or run.
- Diagnostic LED flashing hard-fault codes.
- Visible burn marks, scorched relays, or corrosion on the board.
