Overview
This genuine OEM control board kit (P/N 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS090SFBA0AAA 90,000 BTU gas furnace. The board is the brain of the furnace: it sequences the inducer motor, energizes the hot surface igniter, opens the gas valve, monitors flame via the sensor, and times the blower on and off delays — all while continuously checking the limit and pressure safety switches. A failed board produces some of the most frustrating no-heat symptoms: no response to the thermostat, a dead inducer, no ignition, or a blower that runs constantly. The kit includes the correct board and mounting hardware for a direct, factory-matched replacement that restores proper, safe heating operation.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the control-compartment service panel.
- Document — Photograph every wire and connector on the existing board before disconnecting anything.
- Remove — Unplug all harnesses, release the board from its standoffs, and lift it out.
- Install — Mount the new board, transfer each connector to the matching terminal per your photo, and set any DIP/blower-timing options to match the original.
- Test — Restore power, run a full heat call, and confirm inducer, ignition, flame proof, and blower sequencing all complete normally.
Signs You Need a Replacement
- No response from the furnace when the thermostat calls for heat
- Inducer or igniter never energizes during the start sequence
- Blower runs continuously or won't start
