My furnace will not ignite. What part is bad?

A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Overview

This OEM hot surface igniter (HSI) is the ignition source for the ICP / Tempstar / Heil RGS121SEBA0AAAA gas furnace. On a call for heat, the furnace control board energizes the igniter, which glows red-hot to ignite the gas at the burners. Over time the brittle silicon carbide element develops hairline cracks from thermal cycling, eventually failing open. When that happens the furnace runs its inducer and gas valve sequence but never lights, leaving you with no heat. This listing bundles igniter part #1171306 with the matching igniter wiring kit #1188370 so you have the complete connector and harness needed for a clean replacement.

Installation Guide

Safety First — Shut off gas and disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter.
Access — Remove the furnace burner/control compartment door.
Document — Photograph the igniter bracket position and wire routing before disconnecting.
Remove — Unplug the igniter connector, remove the mounting screw, and lift the old igniter out carefully without touching the element.
Install — Mount the new igniter, install the new wiring kit, and seat the connector. Handle the element by the ceramic base only — skin oils shorten its life.
Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and burners light within seconds.
