Overview
This is the genuine OEM Control Board Kit (part number 1183618) for the ICP Tempstar Heil RGS090STBB0AAA gas furnace. The integrated furnace control board is the brain of your heating system — it manages the ignition sequence, blower timing, gas valve operation, safety lockouts, and fault diagnostics. When this board fails you may see no heat, a furnace that ignites then shuts down, a blower that runs continuously, or flashing error codes on the diagnostic LED. Replacing the board with the correct OEM kit restores reliable, code-compliant operation and the original diagnostic functionality.

Compatibility
Engineered as a direct-fit replacement for the ICP / Tempstar / Heil RGS090STBB0AAA gas furnace. ICP manufactures under several brand names including Heil, Tempstar, Comfortmaker, and others, so this board may also service equivalent models in those families. Always confirm your existing board part number before ordering.
Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the furnace blower-compartment service panel.
- Document — Photograph every wire and connector on the old board before disconnecting anything.
- Remove — Label and unplug the low-voltage and line-voltage harnesses, then remove the mounting screws and lift out the failed board.
- Install — Mount the new board, transfer any jumpers/settings, and reconnect every harness exactly per your photos.
- Test — Restore power, initiate a heat call, and confirm a full ignition cycle with correct blower timing and no fault codes.
Signs You Need a Replacement
- No heat or intermittent ignition with the furnace locking out
- Blower motor runs constantly or fails to start
