Overview
This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) module for the ICP / Tempstar / Heil RGS102STCA0AAA gas furnace. The control board is the brain of the furnace — it sequences the ignition cycle, monitors safety limits and flame signal, controls the inducer and blower motors, and manages the 24V control circuit. When this board fails, the furnace may fail to ignite, short-cycle, lock out, run the blower continuously, or stop responding to the thermostat entirely. Supplied as a complete kit with the correct mounting and connector hardware for a direct OEM replacement.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage at the board with a multimeter before touching any connections.
- Access — Remove the furnace blower-compartment service panel to expose the control board.
- Document — Photograph every wire harness and terminal connection on the existing board before disconnecting anything.
- Remove — Unplug the molex/spade connectors, remove the board mounting screws or standoffs, and lift out the failed board.
- Install — Mount the new board, transfer connectors one at a time to match your photos, and seat each harness fully.
- Test — Restore power, call for heat, and verify the full ignition sequence: inducer, igniter, gas valve, flame proof, and blower.
Signs You Need a Replacement
- Furnace will not start or has no response from the thermostat
- Blower runs continuously or fails to start during a heat call
