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 genuine OEM igniter electrode (part number 1179966) for the ICP / Tempstar / Heil RGS243LSEA0AAAA gas furnace. The hot surface igniter is the heart of the ignition sequence: when the furnace calls for heat, the control board sends voltage to the igniter, which glows red-hot and lights the burner gas. Igniters are brittle and degrade with every heating cycle — the element develops hairline cracks, carbon buildup, or simply burns out. When it fails, the furnace runs the inducer and gas valve sequence but never lights, leaving you with no heat. This direct-fit replacement restores fast, dependable ignition.
