ICP Control Board Kit for RGS180SREA0AAAA — Furnace Ignition Control | Ships Today

Overview

This is the OEM integrated furnace control board kit (Part #1183618) for the ICP / Tempstar / Heil RGS180SREA0AAAA gas furnace. The control board is the brain of the furnace — it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limit and flame-sensing circuits, and controls gas valve timing. When the board fails, the furnace may fail to ignite, short-cycle, lock out, run the blower continuously, or produce no response at the thermostat. This factory-supplied kit includes the replacement board so you restore reliable, code-correct operation.

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 on the existing board before disconnecting anything.
4. Remove — Label and unplug the low-voltage and line-voltage harnesses, then remove the board mounting screws and lift out the old control.
5. Install — Mount the new board, transfer each connector exactly as photographed, and confirm all plugs are fully seated.
6. Test — Restore power, call for heat, and verify the full ignition sequence, blower operation, and clean shutdown.
