Overview

This OEM hot surface igniter (electrode) is the ignition component for the ICP/Tempstar/Heil RGS243SFEA0AAAA gas furnace. On a call for heat, the control board energizes the igniter, which heats to a glowing temperature and ignites the gas at the burner. A cracked, worn, or carbon-fouled igniter is one of the most common causes of furnace no-heat lockouts. OEM part number 1179966 (IGNITOR ELECTRODE) ensures correct resistance, mounting, and timing for reliable, code-compliant ignition.

Installation Guide

Safety First — Disconnect power at the furnace switch and breaker; shut off gas. Verify zero voltage with a multimeter.
Access — Remove the burner compartment service panel.
Document — Photograph the igniter wiring and bracket position before disconnecting.
Remove — Unplug the igniter connector and remove the mounting screw(s). Handle the old igniter by the bracket only — never touch the ceramic element. Lift it clear of the burner.
Install — Mount the new igniter, taking care not to touch the element with bare fingers (skin oils cause hot spots). Reconnect the harness per your photo.
Test — Restore gas and power, run a heat cycle, and confirm the igniter glows and the burner lights smoothly.
