ICP Control Board Kit for RGS102LEBA0AAA — OEM Furnace Control 1183618 | Ships Today

Overview

The OEM integrated furnace control board kit (part 1183618) is the brain of your ICP Tempstar Heil RGS102LEBA0AAA gas furnace. It sequences the entire heating cycle — call for heat, inducer start, igniter warm-up, gas valve actuation, flame verification, and blower on/off timing — while monitoring safety limits and pressure switches. When this board fails, the furnace may stop responding to the thermostat, short-cycle, lock out after ignition, or run the blower continuously. This factory kit includes the replacement board and mounting hardware for a direct fit, eliminating the guesswork of universal boards.

Specifications

Compatibility

Engineered specifically for the ICP / Tempstar / Heil RGS102LEBA0AAA furnace. ICP manufactures under multiple badges (Heil, Tempstar, Comfortmaker, Arcoaire), so this board also services equivalent models built on the same platform. Always confirm your existing board's part number before ordering.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter.
2. Access — Remove the furnace blower-compartment service panel.
3. Document — Photograph every wire and connector position before disconnecting.
4. Remove — Unplug the low-voltage and line-voltage harnesses, release the board standoffs, and lift out the old control.
5. Install — Mount the new board on the standoffs and reconnect each harness exactly per your photos.
6. Test — Restore power, run a heat cycle, and confirm proper ignition, flame sense, and blower timing.

Signs You Need a Replacement

• Furnace does not respond to thermostat calls for heat
• Ignition lockout or repeated short-cycling
