ICP Furnace Control Board Kit for RGS102LFAA0AAA — OEM Ignition Control | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) for the ICP/Tempstar/Heil RGS102LFAA0AAA gas furnace. It is the brain of the appliance: it sequences the inducer, hot surface igniter, gas valve, and blower while continuously monitoring the pressure switch, limit, and flame-sense circuits for safe operation. When the board fails, symptoms range from a completely dead furnace to erratic blower behavior, repeated lockouts, or fault-code flashing on the diagnostic LED. The kit includes the board and the mounting hardware needed for a direct OEM replacement.

Specifications

Compatibility

Designed for the ICP/Tempstar/Heil RGS102LFAA0AAA furnace. ICP-family furnaces (Comfortmaker, Arcoaire, Heil, Tempstar) often share control platforms — match the printed board number to 1183618 and verify the connector layout before installing.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker. Verify zero voltage with a multimeter.
2. Access — Remove the blower compartment service panel.
3. Document — Photograph every wire and connector on the old board before disconnecting anything.
4. Remove — Unplug all harnesses, release the board standoffs/screws, and remove the failed control.
5. Install — Mount the new board, transfer each connector exactly as photographed, and set any speed taps or jumpers to match the original.
6. Test — Restore power and run a full heat cycle, confirming inducer, igniter, gas, and blower sequence correctly with no fault codes.

Signs You Need a Replacement

• Furnace is completely unresponsive to a call for heat
• Blower runs constantly or never starts
• Repeated ignition lockouts with no other failed component found
• Diagnostic LED flashes a hardware/control fault or stays dark with power applied
