Overview

This is a genuine OEM ignitor electrode (ICP part number 1179966) for the ICP/Tempstar/Heil RGS303SFFA0AAAA gas furnace. The igniter glows to a high temperature when energized at the start of a heat cycle, lighting the burners as the gas valve opens. Igniters are a wear item — the element is brittle and degrades with every thermal cycle, eventually cracking or losing the ability to reach ignition temperature. When it fails the furnace goes through its sequence but never lights, leaving the home without heat. Replacing the igniter restores fast, dependable ignition.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker, then verify zero voltage with a multimeter. Shut off the gas supply.
Access — Remove the burner service panel to reach the ignitor at the burner assembly.
Document — Photograph the igniter position and its wire harness routing before disconnecting.
Remove — Unplug the igniter connector and remove the mounting screw(s). Handle only by the ceramic base — never touch the fragile element.
Install — Set the new igniter at the correct depth and angle, secure the screw(s), and reconnect the harness per your photo.
Test — Restore gas and power, then watch a full cycle to confirm the igniter glows and the burners light promptly.
