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 a genuine OEM hot surface igniter for the ICP Tempstar Heil RGS121HTBB0AAAA gas furnace, paired with its matching igniter wiring kit. The hot surface igniter (OEM part 1171306) glows red-hot when energized to ignite the gas at the burners on each heat call, while the wiring kit (OEM part 1188370) provides the correct connector and harness for a clean, code-compliant connection. Igniters are a wear item — the element becomes brittle over time and eventually cracks, leaving you with no heat. Typical failure symptoms include a furnace that clicks and tries to light but never produces flame, repeated ignition lockouts, or a furnace that runs the inducer and blower but delivers cold air.
