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 genuine OEM hot surface igniter kit for the ICP / Heil / Tempstar RGS121LTAB0AAAA gas furnace includes the igniter element (part #1171306) and the matching igniter wiring kit/harness (part #1188370). On each call for heat, the control board sends voltage to the igniter, which glows hot enough to ignite the gas at the burners. Hot surface igniters are a wear item — the brittle silicon-carbide/nitride element degrades with every heating cycle and eventually cracks, producing a no-heat condition where the inducer and gas valve sequence but the burners never light. Replacing the element together with a fresh wiring harness restores reliable ignition.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker; verify zero voltage with a multimeter. Never touch the new igniter element with bare fingers — skin oils shorten its life.
Access — Remove the burner-compartment service panel.
Document — Photograph the igniter position and the wiring/connector routing before disconnecting.
Remove — Unplug the igniter harness, remove the mounting screw(s), and carefully lift out the cracked element.
Install — Mount the new igniter in the same position, connect the new wiring kit, and route the harness clear of hot surfaces.
Test — Restore power, start a heat call, and confirm the igniter glows and the burners light within the normal trial-for-ignition period.

Signs You Need a Replacement
