Overview
This is the OEM control board kit, part number 1183618, for the ICP / Tempstar / Heil RGS090SFCA0AAA gas furnace. The integrated furnace control board is the brain of the system — it manages the entire ignition sequence, monitors safety limits and flame sensing, sequences the inducer and blower motors, and times the heating and cooling cycles. Supplied as a complete kit with mounting and connection hardware for a direct replacement. When the control board fails, the furnace can lose heat entirely, short-cycle, run the blower continuously, or throw fault/flash codes at the diagnostic LED. Because the board ties every component together, replacing a failed one restores correct, safe sequencing across the whole furnace.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter before touching the board.
- Access — Remove the furnace control/blower compartment panel to expose the board.
- Document — Photograph every connector and wire harness on the board before disconnecting — this is the most important step.
- Remove — Unplug each harness, remove the board mounting screws/standoffs, and lift out the old board.
- Install — Mount the new board, transfer any jumpers/links, and reconnect each harness to the matching terminal per your photos.
- Test — Restore power, call for heat and cool, and confirm a full normal sequence with no fault flash codes at the diagnostic LED.
Signs You Need a Replacement
- No heat with no ignition sequence starting
- Blower runs constantly or won't start
