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 (OEM 1171306) ignites the burners on your ICP Tempstar/Heil RGS121HTCB0AAA gas furnace. On each heat call, 120V power heats the igniter element to glowing temperature so it lights the gas as the valve opens. The matching igniter wiring kit (OEM 1188370) is included to ensure a clean, correct electrical connection. Hot surface igniters are a wear item — the brittle silicon-carbide or silicon-nitride element gradually degrades and eventually cracks, leaving you with no heat. A failed igniter is the single most common no-heat furnace complaint, and replacement restores reliable ignition.
