ICP Hot Surface Igniter Kit for RGS120HEAA0AGAA | Ships Today

Overview

This OEM hot surface igniter (part #1171306) and its matching wiring harness kit (part #1188370) ignite the burners on your ICP Tempstar/Heil RGS120HEAA0AGAA gas furnace. On each heat call, the control board energizes the igniter; it glows white-hot and lights the gas as the valve opens. Hot surface igniters are brittle and degrade over thousands of cycles — the most common no-heat furnace failure. Including the wiring kit ensures a clean connection and eliminates the cracked terminals and frayed leads that cause intermittent ignition. Symptoms of a failing igniter include clicking with no light, short-cycling on ignition lockout, and a furnace that runs the inducer and blower but never produces heat.

Installation Guide

1. Safety First – Shut off gas and electrical power; verify zero voltage at the igniter leads with a multimeter.
2. Access – Remove the burner compartment door.
3. Document – Photograph the igniter position and harness routing before disconnecting.
4. Remove – Unplug the igniter harness, remove the mounting screw, and lift out the old igniter without touching the silicon nitride element.
5. Install – Set the new igniter in place (handle by the ceramic base only), secure the screw, and connect the new wiring kit.
6. Test – Restore gas and power; confirm the igniter glows and lights the burners on the first heat call.

Signs You Need a Replacement
