ICP Spark Ignitor Electrode for RGS300SSFA0AAAA — Direct Spark | 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 at startup and, in many designs, also senses the resulting flame to confirm ignition. Its ceramic insulator and electrode tip degrade with heat cycling, and the gap can widen or carbon up, leading to delayed ignition, repeated ignition lockouts, or no ignition at all. A new electrode restores a strong, reliable spark and consistent burner light-off.

Specifications

Compatibility

Direct-fit replacement for the ICP/Tempstar/Heil RGS300SSFA0AAAA gas furnace and other RGS300-series units that use the 1179966 ignitor electrode. Confirm your existing electrode part number and bracket orientation before ordering.

Installation Guide

1. Safety First — Disconnect power at the switch and breaker, shut off the gas, and verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the electrode mounting, wire routing, and gap position before removal.
4. Remove — Disconnect the ignition lead and unscrew the electrode from the burner assembly.
5. Install — Mount the new electrode, confirm proper spark gap and burner alignment, and reconnect the lead per your photo.
6. Test — Restore gas and power, then watch a full ignition cycle for prompt, reliable light-off.

Signs You Need a Replacement

• No spark or weak/intermittent spark at the burner.
• Delayed ignition or rough burner light-off.
• Repeated ignition lockouts on a call for heat.
• Cracked ceramic insulator or carbon-fouled electrode tip.
