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 (part #1171306) and matching igniter wiring kit (part #1188370) are the factory-specified ignition components for the ICP / Heil / Tempstar RGS121LRAB0AAAA gas furnace. The igniter is a 120V hot surface element that glows red-hot to light the main burners on each call for heat. When the igniter cracks, develops hairline fractures, or its silicon nitride element degrades from thousands of heating cycles, the furnace will lock out and fail to fire. Common failure symptoms include the furnace running the inducer and blower but never igniting, repeated ignition lockouts after three tries, or a visibly broken/whitened element. The included wiring kit ensures a clean, corrosion-free electrical connection to the control board.
