ICP Control Board Kit for RGS213LSEA0AAAA — Furnace Ignition Control | Ships Today

Overview

This OEM furnace control board kit (part #1183618) is the central control for your ICP Tempstar/Heil RGS213LSEA0AAAA gas furnace. It sequences ignition, manages blower on/off timing, monitors flame sense, and enforces safety lockouts across the gas valve, igniter, and flame sensor. A failed board commonly results in no ignition, continuous blower operation, short-cycling, or repeated safety lockouts with an error flash code. Genuine OEM boards guarantee correct timing and full compatibility with the furnace's safety circuit.

Specifications

Compatibility

Engineered as the factory replacement for the ICP Tempstar/Heil RGS213LSEA0AAAA gas furnace. Because ICP builds equipment under the Heil, Tempstar, Comfortmaker, and Arcoaire badges, 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.
