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 is the OEM hot surface igniter electrode (part number 1179966) for the ICP / Heil / Tempstar RGS300LDAA0AGAA gas furnace. The igniter heats to a high temperature on each heat call and ignites the burner gas. Because it is repeatedly heated and cooled, it is one of the most common wear parts in any gas furnace and a leading cause of no-heat service calls. Common failure symptoms include the blower running with no heat output, no visible glow during a heat call, a cracked element, or repeated ignition lockouts.
