Heil Hot Surface Igniter Kit for RGS120LFBB0AAA — with Wiring Harness | Ships Today

Overview

This OEM hot surface igniter kit for the ICP/Tempstar/Heil RGS120LFBB0AAA gas furnace includes the igniter element (part 1171306) and the matching igniter wiring kit (part 1188370). On a call for heat, the furnace control board sends line voltage to the igniter, which glows red-hot to light the gas at the burners. Because the brittle silicon-carbide or silicon-nitride element degrades with every heating cycle, the igniter is one of the most common furnace failure points. Symptoms of a failed igniter include no ignition, the furnace cycling on the limit, a cracked or visibly broken element, or an igniter that no longer glows. The included wiring kit ensures a clean OEM connection and avoids reusing brittle, heat-aged leads.

Specifications

Compatibility

Direct OEM replacement for the ICP/Tempstar/Heil/Comfortmaker RGS120LFBB0AAA and related RGS-series gas furnaces. Handle the element only by its ceramic base — skin oils shorten igniter life.

Installation Guide

1. Safety First — Disconnect power at the furnace switch/breaker and verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/control panel.
3. Document — Photograph the igniter mounting and wiring before disconnecting.
4. Remove — Unplug the igniter harness, remove the mounting screw, and carefully withdraw the old element without touching the burners.
5. Install — Mount the new igniter (handle by the base only), install the new wiring kit, and confirm proper position over the burner.
6. Test — Restore power and watch a full heat cycle to confirm the igniter glows and ignites the gas.

Signs You Need a Replacement

• Furnace fails to light on a call for heat
• Igniter does not glow or glows weakly
• Visible crack or break in the element
• Repeated lockouts or short-cycling on the limit
