Overview
The OEM Control Board Kit (part number 1183618) is the integrated furnace control (IFC) that runs the entire heating sequence in your ICP / Tempstar / Heil RGS180LEEA0AAAA furnace. This board manages the ignition sequence, inducer and blower timing, gas valve operation, and all safety interlocks, while monitoring flame sensing and pressure switches. When the control board fails, the furnace may not respond to the thermostat, the inducer or blower may run continuously or not at all, ignition may never initiate, or the unit may repeatedly lock out. Because the board interprets every safety input, a faulty IFC can shut the system down entirely. This genuine OEM kit includes the board and the hardware needed for a clean, code-correct replacement.

Installation Guide

- Access — Remove the furnace blower-compartment service panel to expose the control board.
- Document — Photograph every connector, harness plug, and the dip-switch/jumper settings before disconnecting.
- Remove — Unplug each harness, release the board standoffs or mounting screws, and lift out the old board.
- Install — Mount the new board, transfer any required jumper/dip-switch settings, and reconnect each harness to its matching plug per your photos.
- Test — Restore gas and power, run a full heat cycle, and confirm correct ignition, blower timing, and no fault codes on the diagnostic LED.
