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 assembly for the ICP / Tempstar / Heil RGS121HDBB0AAAA gas furnace, with the matching igniter wiring kit (OEM 1171306 igniter, 1188370 wiring kit). On each call for heat the furnace control board sends 120V to the igniter, which glows white-hot to light the burners. Hot surface igniters are brittle and degrade over time — a cracked or worn element is the single most common cause of no-heat furnace calls. Replacing the igniter together with its wiring harness restores a clean, reliable ignition sequence.
