Overview
This is the OEM furnace control board kit (part #1183618) for the ICP/Tempstar/Heil RGS150HFBA0AAAA. The integrated control board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower motors, monitors the safety circuit (limit switches, pressure switch, flame sensor), and times the heating and cooling cycles. As a kit, it ships with the correct board and mounting/connection components for a clean swap. A failed control board causes erratic behavior: no ignition, blower running constantly or not at all, intermittent operation, or diagnostic LED fault codes. Boards fail from voltage surges, heat stress, relay wear, and corrosion.

Compatibility
Engineered for the ICP/Tempstar/Heil RGS150HFBA0AAAA. Furnace control boards are firmware- and connector-specific, so confirm part #1183618 matches your existing board exactly before ordering — close-looking boards are often not interchangeable.
Installation Guide
- Safety First — Shut off gas and disconnect electrical power. Verify zero voltage at the board's line terminals with a multimeter.
- Access — Remove the furnace control-compartment door.
- Document — Photograph every connector and wire on the old board before unplugging anything.
- Remove — Unplug the harness connectors, remove the board's mounting screws/standoffs, and lift it out.
- Install — Mount the new board, transfer connectors one at a time per your photos, and set any DIP switches/jumpers to match the original.
- Test — Restore gas and power, run a full heat and fan cycle, and confirm correct sequencing with no fault codes.
Signs You Need a Replacement
- Furnace won't start or operates erratically
- Blower runs constantly or never engages
- Diagnostic LED flashing a board/fault code
- Burnt smell, scorched traces, or visible relay damage on the board
