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 is the OEM hot surface igniter electrode (part number 1179966) for the ICP / Tempstar / Heil gas furnace model RGS243STEA0AAAA. The igniter heats to a glowing temperature when the control board energizes it, lighting the burners at the start of every heat cycle. Hot surface igniters are brittle and degrade with each cycle, eventually cracking or failing to reach ignition temperature — the most frequent cause of a furnace that won't light. This OEM electrode is matched to the furnace's resistance and mounting so the ignition sequence times correctly.
