ICP Hot Surface Igniter Kit for RGS090LTAA0AGAA — OEM 1171306 | Ships Today

Overview

This OEM hot surface igniter (part number 1171306), supplied with the matching wiring harness kit (part number 1188370), lights the burners on the ICP/Tempstar/Heil RGS090LTAA0AGAA gas furnace. On each heat call the control board sends voltage to the igniter, which glows incandescent to ignite the gas at the burners. Hot surface igniters are brittle and degrade over thousands of heating cycles — the most common no-heat callback in modern furnaces. Symptoms of a failed igniter include the furnace running its inducer and clicking but never lighting, a visibly cracked or broken element, an igniter that no longer glows, and short-cycling on a flame-proving fault. The included wiring kit ensures a clean, corrosion-free connection.

Specifications

Compatibility

Fits the ICP/Tempstar/Heil RGS090LTAA0AGAA and shared-platform RGS090 series furnaces. Confirm your furnace model on the rating plate before ordering.

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter bracket position and wire routing before removal.
4. Remove — Unplug the igniter harness, unscrew the mounting bracket, and withdraw the old igniter. Handle the new element by the ceramic base only — never touch the silicon nitride/carbide tip.
5. Install — Mount the new igniter at the correct depth over the burner, then connect the new wiring kit.
6. Test — Restore power, start a heat call, and confirm the igniter glows and the burners light promptly.

Signs You Need a Replacement

• Inducer runs and you hear clicking, but burners never light
• Igniter element is visibly cracked or broken
