Heil Hot Surface Igniter for RGS121LFAB0AAAA — With Wiring Kit | Ships Today

Overview

This OEM hot surface igniter (part #1171306) is the component that ignites the burners on your ICP Tempstar Heil RGS121LFAB0AAAA gas furnace. On each heat call the control board sends voltage to the igniter, which glows white-hot to light the gas as it flows across the burners. Hot surface igniters are fragile and degrade with every cycle — the silicon carbide or nitride element eventually cracks, oxidizes, or breaks, leaving the furnace unable to light. This listing includes the matching igniter wiring kit (part #1188370) for a clean, reliable connection. Typical failure symptoms are no heat, a furnace that clicks and tries to start but never ignites, repeated lockouts, or a visibly cracked or broken igniter element.

Installation Guide

1. Safety First — Shut off gas and disconnect power, then verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw; handle the old igniter by its base only.
5. Install — Mount the new igniter (never touch the element), attach the wiring kit, and seat the connector firmly.
6. Test — Restore gas and power, then watch a full ignition cycle to confirm a steady glow and burner light-off.
