Overview
This genuine OEM furnace control board kit (Part No. 1183618) is the integrated ignition control for the ICP/Heil/Tempstar RGS102LTAB0AAA gas furnace. The board is the brain of the furnace: it sequences the ignition cycle, energizes the hot surface igniter and gas valve, monitors flame via the sensor, controls the inducer and blower motor timing, and enforces the safety lockouts that shut the system down on a fault. Because it ties every major component together, a failed control board can produce a wide range of symptoms — no heat, no blower, intermittent operation, repeated lockouts, or error codes flashing on the diagnostic LED. This kit ships with the mounting hardware and instructions needed for a complete board swap.

- Document — Photograph every connector and wire location on the old board before unplugging.
- Remove — Unplug each harness, release the board standoffs or screws, and lift out the old board.

- Test — Restore power, call for heat, and verify a full ignition-to-blower cycle with no fault codes on the diagnostic LED.
