ICP Ignitor Electrode for RGS181LFAA0AGAA — Furnace Ignition | Ships Today

Overview

This OEM ignitor electrode (Part Number 1179966) provides the spark that lights the burners on ICP, Heil, Tempstar, and Comfortmaker gas furnaces such as the RGS181LFAA0AGAA. The electrode sits at the burner assembly and creates a high-voltage arc on a call for heat, igniting the gas/air mixture. Over time the electrode tip erodes, cracks, or the porcelain insulator fails, causing failed ignition, hard starts, or lockouts. A fresh electrode restores reliable, on-the-first-try ignition.

Specifications

Compatibility

Direct-fit replacement for the ICP/Tempstar/Heil RGS181LFAA0AGAA gas furnace and related RGS-series units originally equipped with electrode 1179966. Verify the electrode geometry and mounting against your existing part before installing.

Installation Guide

1. Safety First — Shut off gas and disconnect power, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the electrode position, gap, and wire routing before removal.
4. Remove — Disconnect the ignition lead and unfasten the electrode bracket from the burner assembly.
5. Install — Mount the new electrode at the correct gap and reconnect the ignition lead per your photo.
6. Test — Restore gas and power, then confirm a clean spark and prompt burner ignition.

Signs You Need a Replacement

• Furnace clicks/sparks but burners fail to light.
• Repeated ignition lockouts or hard starts.
• Cracked porcelain insulator or eroded electrode tip.
• Weak, yellow, or inconsistent spark at the burner.
