Overview
This is the genuine OEM control board kit (part number 1183618) for the ICP Tempstar Heil RGS150SFCA0AAAA gas furnace. The integrated furnace control board is the brain of the system — it manages the ignition sequence, monitors safety circuits (limit switches, pressure switches, flame sensing), times the inducer and blower, and coordinates every call for heat from the thermostat. When the board fails, symptoms range from no response at all to erratic cycling, blower or inducer that won't start or won't stop, and ignition lockouts. Supplied as a complete kit, this OEM board restores correct, code-compliant operation and protects the rest of your furnace components.

Compatibility
Direct-fit replacement for the ICP Tempstar Heil RGS150SFCA0AAAA. This control board kit fits related ICP-family furnaces (Tempstar, Heil, Comfortmaker, Arcoaire, KeepRite) built on the same control platform. Because control boards are revision-specific, always confirm part number 1183618 against the label on your existing board before ordering.
Installation Guide
- Safety First — Disconnect electrical power to the furnace and verify zero voltage with a multimeter.
- Access — Remove the furnace control/blower compartment service panel.
- Document — Photograph every wire harness and terminal on the existing board before disconnecting — this is critical for correct reassembly.
- Remove — Unplug all connectors, then unfasten and remove the old control board from its mounting standoffs.
- Install — Mount the new board, then reconnect each harness to the matching terminal per your photos. Set any DIP switches/jumpers to match the original.
- Test — Restore power and run a full heat cycle, confirming proper inducer, igniter, gas valve, and blower sequencing.
Signs You Need a Replacement
- Furnace completely unresponsive to thermostat calls
- Erratic short-cycling or blower/inducer that won't start or stop
- Repeated ignition lockouts with no component fault found
