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 Tempstar Heil RGS121HFCA0AAA includes the igniter (part 1171306) and the matching igniter wiring kit (part 1188370). The hot surface igniter glows red-hot when the furnace control sends voltage to it, lighting the burners at the start of each heating cycle. These silicon-carbide and silicon-nitride igniters are brittle and degrade with every heat cycle, eventually cracking or losing the ability to reach ignition temperature. When the igniter fails, the furnace will go through its pre-purge and inducer sequence but never light, often ending in a lockout and a cold house. Including the wiring kit ensures the connector and leads are fresh, eliminating a common secondary failure point.
