ICP Furnace Control Board Kit for RGS150HECA0AAAA – OEM Integrated Control | Ships Today

Overview

This is the genuine OEM control board kit (part 1183618) for the ICP/Tempstar/Heil RGS150HECA0AAAA gas furnace. The integrated furnace control is the brain of the unit — it sequences the inducer, igniter, gas valve, and blower, monitors safety limits and flame, and stores diagnostic fault codes. The kit ships with the board and the hardware/instructions needed for a complete swap. Control boards typically fail from voltage surges, corrosion, failed relays, or burnt traces around the gas-valve and igniter circuits. Symptoms include a dead furnace with no response to a heat call, blinking diagnostic LED fault codes, the blower or inducer running constantly, or intermittent no-heat lockouts.

Specifications

Compatibility

Engineered for the ICP/Tempstar/Heil RGS150HECA0AAAA and matched across the International Comfort Products furnace family (Heil, Tempstar, Comfortmaker, Arcoaire, KeepRite) that use this control kit. Because board revisions change, verify the OEM part number 1183618 against the board currently installed before ordering.

Installation Guide

1. Safety First – Disconnect electrical power and shut off the gas, then verify zero voltage with a multimeter.
2. Access – Remove the furnace control/blower compartment panel.
3. Document – Photograph every connector and the wiring diagram before unplugging anything; connectors are keyed but labeling prevents mistakes.
4. Remove – Unplug each harness, remove the mounting screws, and lift out the old board.
5. Install – Mount the new board, transfer any jumpers/links per the instructions, and reconnect each harness to its matching plug.
6. Test – Restore power and gas, call for heat, and confirm a full ignition-to-blower sequence with no fault-code flashes.

Signs You Need a Replacement

• Furnace completely unresponsive to a heat call
• Diagnostic LED flashing a control or relay fault code
• Blower or inducer motor that will not shut off
• Visible burnt traces, scorching, or corrosion on the board
