ICP Ignitor Electrode for RGS240HDAA0AAAA — Direct Spark Ignition | Ships Today

Overview

This genuine OEM ignitor electrode (part 1179966) is the ignition component for the ICP / Tempstar / Heil RGS240HDAA0AAAA gas furnace. The electrode delivers the high-voltage spark that lights the burner on a heat call, and on many designs the same or paired electrode also senses flame to confirm ignition. A worn, cracked, or carbon-fouled electrode is one of the most common causes of furnace no-heat and short-cycling lockouts. Because the electrode tip erodes with every ignition cycle, it is a normal wear item that should be inspected during annual service.

Specifications

Compatibility

Designed for the ICP/Tempstar/Heil RGS240HDAA0AAAA and comparable Comfortmaker-family furnaces using direct spark ignition. Match the electrode bracket and gap to your existing assembly before installing.

Installation Guide

1. Safety First — Shut off gas and power, then verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the electrode wire routing and mounting position.
4. Remove — Disconnect the high-voltage lead, remove the mounting screw, and lift out the old electrode without bending the bracket.
5. Install — Seat the new electrode, set the spark gap per spec, and reconnect the ignition lead.
6. Test — Restore gas and power, then confirm a clean spark and reliable burner light-off.

Signs You Need a Replacement

• Furnace clicks but burners won't light.
• Repeated ignition-failure lockouts or short cycling.
• Cracked ceramic insulator or eroded/blackened electrode tip.
• Weak, intermittent, or no visible spark.
