ICP Igniter Electrode for RGS303STAA0AAAA – OEM 1179966 Ignition Electrode | Ships Today

Overview

This genuine OEM igniter electrode, factory part number 1179966, is the ignition component responsible for lighting the burners in ICP, Tempstar, Heil, and Comfortmaker gas furnaces such as the RGS303STAA0AAAA. The electrode positions precisely in the burner flame path to initiate and prove ignition each heating cycle. Because it endures repeated thermal and electrical stress, the electrode and its ceramic insulator eventually crack, erode, or carbon-foul — leading to failed light-off, delayed ignition, or lockout after several retries. Replacing it with the correct OEM electrode restores consistent, on-demand ignition and prevents nuisance no-heat calls.

Specifications

Compatibility

Direct factory replacement for ICP/Tempstar/Heil/Comfortmaker gas furnaces using OEM igniter electrode 1179966, including the RGS303STAA0AAAA. Confirm the part number and bracket orientation against your original before installing.

Installation Guide

1. Safety First – Disconnect electrical power and shut off the gas supply, then verify zero voltage with a multimeter.
2. Access – Remove the burner compartment service panel.
3. Document – Photograph the electrode's mounting position, gap, and wire routing.
4. Remove – Unplug the ignition lead and unscrew the electrode bracket; handle the ceramic by the base only.
5. Install – Mount the new electrode at the factory gap and reconnect the ignition lead.
6. Test – Restore gas and power, then run a full heat cycle to confirm clean ignition.

Signs You Need a Replacement

• Furnace clicks/sparks but burners won't light
• Cracked ceramic insulator or visibly eroded electrode tip
• Delayed ignition or a small "poof" at startup
• Repeated ignition retries ending in lockout
