ICP Control Board Kit for RGS213LTAA0AAAA — Furnace Ignition Control | Ships Today

Overview

This OEM furnace control board kit (part #1183618) is the brain of your ICP Tempstar/Heil RGS213LTAA0AAAA gas furnace. It manages the ignition sequence, blower timing, safety lockouts, and communication between the thermostat, gas valve, igniter, and flame sensor. When this board fails, the furnace may fail to ignite, short-cycle, lock out, or run the blower continuously. A flashing diagnostic LED with no heat output is a classic symptom of a failed control board. Installing a genuine OEM board ensures correct timing and full safety-circuit compatibility.

Specifications

Compatibility

Engineered as the factory replacement for the ICP Tempstar/Heil RGS213LTAA0AAAA gas furnace. ICP manufactures equipment under the Heil, Tempstar, Comfortmaker, and Arcoaire badges, so this board may also service equivalent models in those lines — always confirm against your existing board's part number.

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.
4. Remove — Unplug the wiring harnesses, release the board mounting standoffs/screws, and lift out the old board.
5. Install — Mount the new board on the standoffs and reconnect every harness exactly per your photos.
6. Test — Restore power, initiate a heat call, and verify the full ignition sequence and blower operation.
