ICP Igniter Electrode for RGS303SEFA0AAAA — OEM Ignition Electrode | Ships Today

Overview

This genuine OEM igniter electrode, part number 1179966, is the ignition component responsible for lighting the burners in your ICP/Tempstar/Heil gas furnace. On each heat call the electrode delivers the spark or ignition source that ignites the gas at the burner, and it works alongside the flame-sensing circuit to confirm a stable flame. A cracked ceramic insulator, eroded electrode tip, or fouled surface prevents reliable ignition. The most common failure symptom is a furnace that clicks or sparks repeatedly but never lights, ignites on a delay, or short-cycles on ignition lockout. Replacing a worn electrode restores fast, dependable burner ignition and prevents nuisance lockouts on cold mornings.

Installation Guide

1. Safety First — Disconnect power and shut off the gas supply; verify zero voltage with a multimeter.
2. Access — Remove the furnace service panel to reach the burner assembly.
3. Document — Photograph the electrode position, gap, and wiring before removal.
4. Remove — Disconnect the ignition lead and unscrew the old electrode from the burner bracket, handling the ceramic carefully.
5. Install — Mount the new electrode, set it to the factory gap, and reconnect the lead per your photo.
6. Test — Restore gas and power, then confirm clean ignition and steady flame on a heat call.

Signs You Need a Replacement

• Furnace sparks or clicks repeatedly but burners won't light.
• Cracked or chipped ceramic insulator on the electrode.
• Delayed ignition or rough, delayed light-off (a small "poof").
• Repeated ignition lockouts or short cycling on startup.
