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 genuine OEM hot surface igniter kit for the ICP/Tempstar/Heil RGS121HRCB0AAA includes the igniter (P/N 1171306) and its dedicated wiring harness kit (P/N 1188370). On a call for heat, the control board energizes the igniter, which glows red-hot to light the gas burners. The included wiring kit ensures a clean, correctly terminated connection and is the recommended companion when replacing a failed igniter. Hot surface igniters are brittle and degrade over time, making them one of the most frequent no-heat failure points. A fresh igniter and harness restore fast, reliable ignition.
