Overview
This OEM control board kit (part 1183618) is the integrated furnace control for the ICP Tempstar Heil RGS101HTCB0AAA. The board is the brain of the furnace — it sequences the entire heating cycle, energizing the inducer, igniter, gas valve, and blower in the correct order while monitoring safety inputs like the pressure switch, limit switches, and flame sensor. It also runs the cooling and continuous-fan blower modes and stores diagnostic fault codes on its LED. When the control board fails, the furnace may be completely dead, stuck in lockout, short-cycle, or run the blower continuously. This complete kit is the direct OEM replacement and typically includes the mounting hardware and instructions needed for a clean swap.

- Document — Photograph every wire harness and connector position on the old board before disconnecting.
- Remove — Unplug each connector, remove the mounting screws or standoffs, and lift out the failed board.
- Install — Mount the new board from the kit and reconnect each harness exactly as photographed; set any DIP switches or jumpers to match the original.
- Test — Restore gas and power, run a full heating and blower cycle, and confirm correct sequencing with no fault codes.
