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 OEM hot surface igniter kit for the ICP Tempstar Heil RGS120LFAA0AAA includes the igniter (part 1171306) and the matching igniter wiring kit / harness (part 1188370). The hot surface igniter is the component that glows red-hot on a call for heat to ignite the gas at the burners. These igniters are fragile and wear out with every heating cycle as the element oxidizes and grows brittle, eventually cracking or failing to reach ignition temperature. The included wiring kit ensures a clean, corrosion-free electrical connection so the new igniter receives full voltage. Together they restore fast, reliable ignition and end no-heat call-backs caused by a failed igniter.
