ICP Ignitor Electrode for RGS300HREA0AAAA — Direct Spark Ignition | Ships Today

Overview

The ignitor electrode (OEM part 1179966) is the spark-rod assembly that lights the burner gas in your ICP RGS300HREA0AAAA furnace and provides flame rectification feedback to the control board. The control sends a high-voltage spark across the electrode gap to ignite the gas, then reads the micro-amp flame current through the same rod to confirm a stable flame. A cracked ceramic insulator, eroded electrode tip, or carbon-fouled rod produces weak or no spark and false flame-loss faults — the furnace ignites, then locks out on a no-flame-sensed error, or never lights at all.

Specifications

Compatibility

Direct OEM fit for the ICP/Heil/Tempstar RGS300HREA0AAAA and shared-platform furnaces using this direct-spark ignition assembly. Match the bracket and rod geometry to your existing electrode 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 the ignition lead routing.
4. Remove — Disconnect the high-voltage ignition lead, unscrew the electrode bracket, and lift the assembly clear of the burner.
5. Install — Mount the new electrode so the tip sits in the burner flame path at the factory gap, then reconnect the ignition lead.
6. Test — Restore gas and power, start a heat call, and confirm a strong spark, clean light-off, and a stable sensed flame with no lockout.

Signs You Need a Replacement

• Furnace clicks/sparks but burners won't light.
• Ignites then shuts down on a flame-sense / flame-loss lockout.
• Cracked or chipped ceramic insulator, or a heavily eroded electrode tip.
• Repeated ignition-retry cycling before the furnace gives up.
