ICP Hot Surface Igniter Electrode for RGS303LDEA0AAAA — OEM 1179966 | Ships Today

Overview

This is a genuine OEM igniter electrode (part number 1179966) for the ICP / Tempstar / Heil RGS303LDEA0AAAA gas furnace. The igniter heats on each call for heat to light the burners; because it cycles to high temperature thousands of times, it is a wear item and one of the most common no-heat failures. A cracked or aged igniter glows weakly or not at all, causing the furnace to lock out after several failed ignition attempts. Replacing the igniter restores reliable, on-demand burner ignition.

Specifications

Compatibility

Built for the ICP-manufactured RGS303LDEA0AAAA furnace and shared across the Tempstar, Heil and Comfortmaker brands. Match the OEM number 1179966 and the igniter's mounting and connector style to your existing part before installing. Handle the igniter element only by its ceramic base — skin oils can shorten its life.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, and verify zero voltage with a multimeter. Allow a hot igniter to cool fully.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the igniter mounting position and wiring connector before removal.
4. Remove — Unplug the igniter connector, remove the mounting screw(s), and carefully withdraw the old igniter from the burner assembly.
5. Install — Seat the new igniter at the correct position over the burner, fasten it, and reconnect the plug — touching only the ceramic base.
6. Test — Restore power, call for heat, and confirm the igniter glows bright orange and the burners light promptly.

Signs You Need a Replacement

• Furnace blower runs but burners never light (no heat)
• Visible crack or chip in the igniter element
• Igniter glows dim, uneven, or not at all
