ICP Igniter Electrode for RGS300SEFA0AAAA — Direct Spark | Ships Today

Overview

This is a genuine OEM igniter electrode, ICP part number 1179966, for the ICP, Tempstar, and Heil RGS300SEFA0AAAA gas furnace. The electrode produces the high-voltage spark that lights the burner on a call for heat and, in many designs, also serves to sense the resulting flame. A cracked ceramic insulator, eroded electrode tip, or incorrect spark gap will cause failed ignition, repeated retries, or flame-sense lockouts.

Replacing a worn electrode restores reliable first-try ignition and prevents the comfort and safety lockouts that come from a weak or missing spark.

Specifications

Compatibility

Built for the ICP / Tempstar / Heil RGS300SEFA0AAAA and related RGS-series gas furnaces specifying OEM part 1179966. Verify the electrode shape and mounting against your existing part before ordering.

Installation Guide

1. Safety First — Disconnect power and shut off the gas supply; verify zero voltage with a multimeter.
2. Access — Remove the burner/service panel to reach the ignition assembly.
3. Document — Photograph the electrode position, wire routing, and spark gap before removal.
4. Remove — Disconnect the ignition lead and unscrew the electrode bracket from the burner.
5. Install — Mount the new electrode, set the spark gap to OEM spec, and reconnect the lead per your photo.
6. Test — Restore gas and power, call for heat, and confirm a strong spark and stable flame.

Signs You Need a Replacement

• Furnace clicks but burner fails to light
• Repeated ignition retries or hard lockout
• Cracked or carbon-fouled ceramic insulator
• Weak, erratic, or missing spark at the electrode tip
