Overview
This genuine OEM furnace control board kit (part number 1183618) is the electronic brain of the ICP/Tempstar/Heil RGS102LRBA0AAA gas furnace. It manages the entire heating sequence — reading the thermostat call, running the inducer and pressure-switch proof, energizing the hot surface igniter, opening the gas valve, timing the blower on/off delays, and monitoring flame sense and safety limits. The board also stores diagnostic flash codes that pinpoint faults. Control boards fail from power surges, heat stress, corroded relays, and cracked solder joints, producing symptoms ranging from no heat to short cycling to a blower that runs constantly. Supplied as a kit for direct OEM replacement and reliable sequencing.

Installation Guide
- Safety First — Disconnect power at the furnace switch/breaker and verify zero voltage with a multimeter.
- Access — Remove the control-compartment panel.
- Document — Photograph every harness connector and wire location — this is the most important step for a board swap.
- Remove — Unplug all connectors, release the board's standoffs/screws, and lift out the old board.
- Install — Mount the new board, transfer each connector to the identical position per your photos, and set any required dip switches/jumpers to match.
- Test — Restore power, run a full heat cycle, and confirm proper sequencing with no error flash codes.
Signs You Need a Replacement
- Furnace produces no heat with no igniter or inducer response
- Short cycling or erratic, inconsistent operation
- Blower runs continuously or fails to start
