Overview
This OEM control board kit (OEM #1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS102SECB0AAA. It is the brain of the furnace, sequencing the inducer motor, hot surface igniter, gas valve, and blower while monitoring limit switches, pressure switches, and flame sense for safe operation. The board also runs onboard diagnostics, flashing fault codes through its LED. Control boards fail from heat fatigue, line-voltage surges, cracked solder joints, blown onboard fuses, and burned relays. Symptoms include a completely dead furnace, no inducer or igniter sequence, a blower that runs constantly or not at all, and erratic or absent diagnostic codes. Sold as a kit with the mounting hardware and connectors needed for a clean swap.

Installation Guide

- Access — Remove the blower compartment door to expose the control board.
- Document — Photograph every plug and terminal connection before removing a single wire.
- Remove — Unplug the harnesses, release the board standoffs or screws, and lift the old board out.
- Install — Mount the new board and reconnect each harness to the matching terminal per your photo.
- Test — Restore power and run a full heat and fan cycle, confirming a normal startup sequence and steady diagnostic LED.
Signs You Need a Replacement
