ICP Ignitor Electrode for RGS300LTFA0AAAA — OEM Spark Igniter | Ships Today

Overview

This is a genuine OEM ignitor electrode (part number 1179966) for ICP, Tempstar, and Heil gas furnaces. The electrode delivers the high-voltage spark that ignites the burner gas on each heat call, and on many designs the same or paired electrode also serves as the flame-sensing rod. A cracked ceramic insulator, eroded electrode tip, or carbon buildup leads to weak or no spark, failed ignition, and lockout. If your furnace clicks repeatedly but never lights, or lights then drops out on flame failure, the ignitor electrode is a prime suspect.

Specifications

Compatibility

Factory replacement for ICP/Tempstar/Heil model RGS300LTFA0AAAA and related RGS300 series furnaces using ignitor electrode 1179966. Confirm the OEM number and bracket orientation against your existing electrode.

Installation Guide

1. Safety First — Shut off the gas, disconnect power, and 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 disconnecting.
4. Remove — Disconnect the high-voltage lead and unfasten the electrode bracket; avoid touching the ceramic with bare fingers.
5. Install — Mount the new electrode, set the correct spark gap, and reconnect the ignition lead.
6. Test — Restore gas and power and confirm a strong, consistent spark and clean burner light-off.

Signs You Need a Replacement

• Furnace clicks but burners never ignite
• Weak, intermittent, or no visible spark
• Cracked or chipped ceramic insulator
• Repeated ignition lockouts or flame-failure faults
