ICP Control Board Kit for RGS210LFEA0AAAA — OEM 1183618 Furnace Control | Ships Today

Overview

This OEM Control Board Kit (part number 1183618) is the integrated furnace control board for the ICP/Tempstar/Heil RGS210LFEA0AAAA gas furnace. The board manages the entire heating sequence — inducer operation, igniter timing, gas valve actuation, flame sensing, and blower control — while monitoring safety limits and pressure switches. When this board fails, the furnace may fail to ignite, short-cycle, lock out, or stop responding to the thermostat entirely. A blinking diagnostic LED with no heat call response is a common symptom of board failure. This kit ships complete and ready to install as a direct replacement.

Specifications

Compatibility

Engineered for the ICP RGS210LFEA0AAAA gas furnace and shared Tempstar/Heil/Comfortmaker platform variants using the same control architecture. Always verify your existing board part number against 1183618 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 on the existing board.
4. Remove — Unplug each harness, release the board standoffs/screws, and lift out the failed control.
5. Install — Mount the new 1183618 board, reconnect every harness exactly per your photos.
6. Test — Restore power, initiate a heat call, and confirm a full ignition and blower cycle with no fault codes.

Signs You Need a Replacement

• Furnace will not respond to a thermostat heat call
