Overview
This is a genuine OEM control board kit, part number 1183618, for ICP, Heil, and Tempstar package units such as the RGS210HEAA0AAAA. The integrated furnace control board is the brain of the unit: it sequences the entire heat cycle, runs the igniter, opens the gas valve, monitors safeties (limits, pressure/rollout switches, flame sense), times the inducer and blower, and stores fault codes on its diagnostic LED. The kit ships with the mounting hardware and connectors needed for a clean swap. Control boards fail from power surges, corrosion, cracked solder joints, and failed relays — symptoms include a completely dead unit, no ignition sequence, the blower running constantly or not at all, or a fault LED flashing a specific error pattern. Replacing the board restores full automatic operation and clears board-level lockouts.

Compatibility
Fits the ICP/Tempstar/Heil RGS210HEAA0AAAA gas package unit and related RGS210-series models that use the 1183618 control board kit. Match the part number to your existing board before ordering, as control boards are model-specific.
Installation Guide
- Safety First — Disconnect power and verify zero voltage with a multimeter before touching the board.
- Access — Remove the control-compartment panel to expose the board.
- Document — Photograph every harness and plug location; note any DIP switch or jumper settings.
- Remove — Unplug each connector, release the board standoffs, and lift out the old board.
- Install — Mount the new board on the supplied standoffs, transfer all connectors to the matching headers per your photo, and replicate the DIP/jumper settings.
- Test — Restore power and run a full heat and blower cycle; confirm a steady (normal) LED with no fault codes.
Signs You Need a Replacement
- Unit completely dead with no response to a thermostat call.
- No ignition sequence — inducer or igniter never energizes.
- Blower runs constantly or won't run at all.
- Diagnostic LED flashing a hard-fault or internal-error code.
