Overview
This OEM control board kit (part 1183618) is the integrated furnace control for the ICP Tempstar Heil RGS102LRAB0AAA gas furnace. The board is the brain of the system: it sequences the inducer, hot surface igniter, gas valve, and blower, monitors safety limits and flame sense, and stores fault/diagnostic codes on its LED. When the board fails — from power surges, corrosion, burnt relays, or cracked solder joints — symptoms range from no ignition to a blower that won't start or stop, or no response at all to a thermostat call. This kit ships with the board and mounting hardware to restore full furnace operation.

Installation Guide
- Safety First — Disconnect power at the furnace switch and breaker, verify zero voltage with a multimeter.
- Access — Remove the blower compartment service panel.
- Document — Photo every connector and the full wire harness before disconnecting.
- Remove — Unplug each harness, remove the mounting screws, and lift out the old board.
- Install — Mount the new board, reconnect every harness to its matching plug per your photo, and set any DIP switches to match the original.
- Test — Restore power, call for heat, and verify the full sequence: inducer, igniter, flame, then blower. Check the diagnostic LED for a steady/normal code.
Signs You Need a Replacement
- No response to a thermostat heat call
- Blower runs constantly or never starts
