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 genuine OEM ignitor electrode (part number 1179966) is the hot surface igniter for the ICP / Heil / Tempstar RGS300LREA0AAAA gas furnace. On a call for heat, the control board sends power to the igniter, which heats to a glowing temperature to ignite the gas at the burners. Hot surface igniters are a common wear item — the brittle silicon-carbide or silicon-nitride element degrades over thousands of heating cycles until it cracks or fails to reach ignition temperature. The result is no heat, repeated ignition lockouts, or a furnace that clicks and tries but never lights. Replacing the igniter with the correct OEM electrode restores fast, dependable ignition and clears nuisance lockout faults.

Access — Remove the burner-compartment service panel.
Document — Photograph the igniter position, bracket, and wire routing before disconnecting.
Remove — Unplug the igniter harness and remove the mounting screw; handle the ceramic base only, never the fragile element.
Install — Mount the new igniter, taking care not to touch the heating element with bare fingers, and reconnect the harness.
Test — Restore gas and power, then watch a full ignition sequence to confirm the igniter glows and the burners light.
