Overview
This OEM integrated furnace control board kit (part 1183618) is the brain of the ICP/Heil/Tempstar RGS090SEBB0AAA gas furnace. It manages the entire heating sequence — inducer startup, hot surface igniter timing, gas valve control, flame sensing, blower fan delays, and all safety lockouts. A failed board typically presents as a dead furnace, erratic operation, blower that will not start or will not stop, or repeated ignition lockouts with no other identifiable cause. Power surges, corroded relays, and burned flame-sense circuits are the usual culprits. This genuine OEM kit ships with the correct firmware and relay configuration for your furnace, eliminating the guesswork of aftermarket boards.

- Document — Photograph every wire and connector position before disconnecting anything.
- Remove — Unplug all harnesses, remove the mounting screws, and lift out the old board.
- Install — Mount the new board, transfer each wire to the matching terminal per your photos, and set any jumpers or DIP switches identically.
- Test — Restore power and run a full heat cycle, confirming proper ignition, flame sensing, and blower timing.
