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 (part 1171306) with matching igniter wiring kit (part 1188370) fits the ICP / Tempstar / Heil RGS121LSCA0AAA gas furnace. On every heating call, the control board sends voltage to the igniter, which glows red-hot to ignite the gas at the burners. Hot surface igniters are brittle and degrade over time from repeated thermal cycling, oxidation, and even a fingertip touch on the element. A cracked or worn igniter is the leading cause of no-heat furnace calls. This kit includes both the igniter and the OEM wiring harness, so you replace the element and its often-brittle leads together for a clean, reliable repair.
