Overview
This OEM control board kit is the brain of the ICP Tempstar Heil RGS150HECB0AAAA 150,000 BTU gas furnace. The integrated furnace control sequences the inducer, igniter, gas valve, and blower, monitors the flame sensor and pressure/limit switches, and runs the safety lockout logic. Boards fail from heat-stressed relays, blown onboard fuses, surge damage, and cracked solder joints — symptoms include a furnace that's completely dead, a blower that never starts (or never stops), no ignition sequence, or a diagnostic LED flashing a fault code. Part 1183618 ships as a complete kit so you can restore reliable operation.

Compatibility
Designed for the ICP / Tempstar / Heil RGS150HECB0AAAA furnace and RGS-series sister models that specify control board 1183618. ICP-family brands (Tempstar, Heil, Comfortmaker, Arcoaire) share this control platform — verify the board callout in your unit's parts list before ordering.
Installation Guide
- Safety First — Disconnect furnace power at the disconnect or breaker and verify zero voltage with a multimeter.
- Access — Remove the blower-compartment door to expose the control board.
- Document — Photograph every wire and connector position; label harnesses if needed. This is the most important step.
- Remove — Unplug all connectors, remove the board mounting screws, and lift out the old board.
- Install — Mount the new 1183618 board, then reconnect every harness exactly per your photo. Set any DIP switches / heat-anticipator jumpers to match the original.
- Test — Restore power and run a full heat cycle; confirm normal ignition sequence and that the diagnostic LED shows normal operation.
Signs You Need a Replacement
- Furnace is completely unresponsive with no ignition sequence.
- Blower runs continuously or never engages on a heat call.
- Diagnostic LED flashing a hard-fault or internal-control error code.
- Visible scorching, a blown onboard fuse, or burnt relay on the board.
