Overview
The OEM Control Board Kit (Part No. 1183618) is the integrated furnace control (IFC) — the brain of your ICP/Tempstar/Heil RGS102HFCA0AAA gas furnace. It manages the entire heating sequence: it reads the thermostat call, runs the inducer and pressure-switch proving, energizes the hot surface igniter, opens the gas valve, monitors flame via the sensor, and times the blower on and off delays. It also handles safety lockouts and flashes diagnostic fault codes via an onboard LED. A failed control board produces some of the most frustrating furnace symptoms — no response to the thermostat, blower running constantly, ignition that never starts, or intermittent lockouts. This genuine kit includes the board and the mounting hardware needed for a direct factory-spec replacement.

Compatibility
Engineered for the ICP, Tempstar, and Heil RGS102HFCA0AAA gas furnace and related RGS-series models that use this integrated furnace control.

Installation Guide

- Access — Remove the furnace control/blower compartment panel to expose the board.
- Document — Photograph every wire harness and plug connection before unplugging anything.
- Remove — Unplug all connectors, remove the mounting screws, and lift out the old control board.
- Install — Mount the new board with the included hardware and reconnect each harness to the matching plug per your photos.
- Test — Restore power and gas, run a full heat cycle, and confirm proper ignition, blower timing, and no fault codes on the diagnostic LED.
