ICP Furnace Control Board Kit for RGS102LFBB0AAA — OEM 1183618 | Ships Today

Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control (IFC) for the ICP / Tempstar / Heil RGS102LFBB0AAA. The board is the brain of the furnace: it sequences the ignition cycle, runs the inducer and blower motors, monitors safety limits and the flame sensor, and times each stage of heating. When the board fails, the furnace can stop responding to the thermostat, short-cycle, skip ignition, run the blower continuously, or flash diagnostic fault codes. This OEM-spec replacement kit restores correct ignition timing, blower control, and safety monitoring for reliable furnace operation.

Installation Guide

1. Safety First — Disconnect electrical power at the furnace switch and breaker. Verify zero voltage with a multimeter.
2. Access — Remove the blower compartment/control service panel to expose the board.
3. Document — Photograph every harness plug and wire location before disconnecting — this is the most important step.
4. Remove — Unplug each connector, release the board standoffs/screws, and lift out the old board.
5. Install — Mount the new board, transfer every connector to the matching header per your photos, and confirm each plug is fully seated.
6. Test — Restore power, call for heat, and verify the full sequence: inducer, igniter, ignition, and blower with no fault codes.
