ICP Hot Surface Igniter for RGS120LSBA0AAA with Wiring Kit | Ships Today

Overview

This is the genuine OEM hot surface igniter (part #1171306) for the ICP / Tempstar / Heil RGS120LSBA0AAA gas furnace, supplied with the matching igniter wiring kit (part #1188370). The hot surface igniter is the component that glows red-hot at the start of every heating cycle to light the gas at the burners. It is one of the most common failure points in a modern furnace because the silicon-carbide or nitride element is brittle and degrades with every ignition cycle. When it fails, the furnace will not produce heat even though the control board, blower, and gas valve are working normally.

Typical failure symptoms include a furnace that runs the inducer and blower but never lights, an igniter that no longer glows, a cracked or visibly burned-out element, or a lockout after several failed ignition attempts. The included wiring kit ensures the connector and harness are replaced together, which prevents intermittent heat-no-heat problems caused by a heat-fatigued connector at the igniter.

Specifications

Compatibility

Designed as a direct OEM replacement for the ICP/Tempstar/Heil RGS120LSBA0AAA gas furnace. It also fits many other ICP-family furnaces that originally shipped with igniter 1171306 — always confirm against your unit's parts list before ordering.

Installation Guide

1. Safety First – Disconnect power at the furnace switch and verify zero voltage with a multimeter. Shut off the gas supply.
2. Access – Remove the burner-compartment service panel.
3. Document – Photograph the igniter mount and wiring connector before disconnecting.
4. Remove – Unplug the igniter connector, remove the mounting screw, and carefully withdraw the old igniter without touching the element with bare fingers.
5. Install – Mount the new igniter, install the new wiring kit, and reconnect per your photo. Never touch the silicon element directly — skin oils shorten its life.
6. Test – Restore gas and power, then run a heating cycle and confirm the element glows and the burners light cleanly.

Signs You Need a Replacement

• Furnace runs the inducer/blower but never lights.
• Igniter does not glow when commanded by the control board.
• Visible cracks, blistering, or burn-out on the element.
• Furnace locks out after repeated failed ignition attempts.
