Overview
This is a genuine OEM furnace control board kit, OEM part number 1183618, for the ICP / Tempstar / Heil RGS210SFAA0AAAA gas furnace. The integrated furnace control board is the brain of the appliance: it sequences the entire heating cycle, energizing the inducer, proving pressure switches, firing the igniter, opening the gas valve, monitoring flame, and timing the blower on and off. It also manages safety lockouts and flashes diagnostic fault codes via its onboard LED. Control boards fail from heat stress, voltage surges, corroded relays, and cracked solder joints. When the board fails you typically get a completely dead furnace, a unit stuck on the blower, an inducer that won't start, or a steady or erratic diagnostic LED. This kit includes the replacement board and the hardware needed to install it.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
- Access — Remove the control compartment service panel.
- Document — Photograph every harness connector and wire location on the old board before unplugging anything.
- Remove — Unplug each connector, remove the mounting screws, and lift out the failed board.
- Install — Mount the new board, then transfer each connector to the matching terminal exactly as photographed; set any DIP switches to match the original.
- Test — Restore power, run a full heat cycle, and confirm proper ignition sequence, blower timing, and a normal diagnostic LED.
Signs You Need a Replacement
- Completely dead furnace with no response to a call for heat.
- Diagnostic LED that is off, stuck on, or flashing an internal control fault code.
- Inducer, igniter, or blower that won't energize even with good components.
