Overview
This OEM integrated furnace control board kit (OEM part #1183618) is the brain of your ICP RGS102LSBA0AAA furnace. It sequences the entire heating cycle — energizing the inducer, proving the pressure switch, powering the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower on/off delays. It also coordinates cooling and continuous-fan operation. When a control board fails, the furnace may be completely dead, stuck running the blower, intermittently no-heat, or throwing fault codes on its diagnostic LED. Boards typically fail from power surges, overheating, cracked solder joints, or burnt relays. This kit is the exact OEM replacement and restores full, code-compliant control of every safety and timing function.

- Access — Remove the furnace control/blower compartment panel.
- Document — Photograph every plug, terminal, and wire color on the old board before removing anything.
- Remove — Unplug all connectors and 24V terminals, then unscrew the board from its standoffs.
- Install — Mount the new board, transfer each connector to the matching position, and set any dip switches/jumpers to match the original.
- Test — Restore power and gas, then run a full heat and cool cycle while watching the diagnostic LED for fault codes.
