Overview
This OEM control board kit (part #1183618) is the brain of the ICP/Heil/Tempstar RGS102HFAB0AAA gas furnace. It sequences the entire heat cycle — energizing the inducer, proving pressure, firing the hot surface igniter, opening the gas valve, and timing the blower on/off delays. It also monitors flame, limit, and rollout safeties and reports fault codes via its diagnostic LED. A failed board produces erratic, hard-to-diagnose behavior: blowers that won't shut off, ignition sequences that never start, or a completely dead furnace. The kit ships with the OEM board and mounting hardware for a direct replacement.

Installation Guide
- Safety First – Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
- Access – Remove the furnace control/blower access panel.
- Document – Photograph every wire and connector on the board before removing anything; label harnesses if needed.
- Remove – Disconnect all plugs and spade terminals, remove the mounting screws, and lift out the old board.
- Install – Mount the new board, then reconnect each harness exactly per your photos. Confirm the line-voltage and 24V connections are correct.
- Test – Restore power, run a full heat cycle, and watch the diagnostic LED for a normal (no-fault) code.
Signs You Need a Replacement
- Furnace is completely dead with no LED activity
- Blower runs constantly or won't start on a heat call
- Ignition sequence never begins despite good igniter and gas valve
- Diagnostic LED flashes a hard-fault code that persists after resetting safeties
