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.

Overview

This OEM hot surface igniter kit for the ICP RGS120LTBB0AAA gas furnace includes the igniter (part 1171306) and its wiring kit/harness (part 1188370). The hot surface igniter glows red-hot on each heat call to ignite the gas at the burners. These elements are brittle and degrade with thermal cycling, eventually cracking or losing the ability to reach ignition temperature. When the igniter fails, the furnace will not light and typically locks out after several failed trials. The included wiring kit ensures a clean, correct electrical connection.
