Overview
This OEM control board kit (part number 1183618) is the integrated furnace control for the ICP / Tempstar / Heil RGS102HSBA0AAA. The board is the brain of the furnace: it sequences the inducer, igniter, gas valve, and blower, monitors limit and pressure safeties, and runs the diagnostic LED flash codes used during service. A board failure can show up as a dead furnace, a unit stuck in lockout, a blower that never starts or never stops, or erratic short-cycling. Because it ties every major component together, a degraded board often mimics other part failures — replacing it with the correct OEM kit restores proper timing and safety logic in one step. The kit includes the board and mounting hardware for a direct swap.

- Document — Photograph every connector and wire location; note any DIP switch or jumper settings on the old board.
- Remove — Unplug the harnesses, remove the mounting screws, and lift out the old board.
- Install — Mount the new board, match any DIP/jumper settings, and reconnect each harness to its keyed plug per your photos.
- Test — Restore power and run a full heat and blower cycle; confirm normal flash codes and operation.
