ICP Ignitor Electrode for RGS300STFA0AAAA — Spark Ignition | Ships Today

Overview

This is the genuine OEM ignitor electrode (part 1179966) for the ICP / Tempstar / Heil RGS300STFA0AAAA gas furnace. The ignitor electrode generates the high-voltage spark that lights the burner gas on each heating cycle, and on many systems the same or paired electrode also serves as the flame-sense rod confirming the burner lit. A cracked ceramic insulator, eroded electrode tip, carbon buildup, or an incorrect spark gap leads to ignition failure, delayed ignition with a rough light-off, or repeated lockouts where the furnace tries several times and then shuts down. Replacing the electrode restores a clean, consistent spark and reliable burner ignition.

Specifications

Compatibility

Direct-fit OEM replacement for the ICP / Tempstar / Heil RGS300STFA0AAAA furnace and related RGS-series units using ignitor electrode part 1179966. Confirm the part number and mounting orientation against your existing electrode before ordering.

Installation Guide

1. Safety First — Shut off the 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, ignition lead, and spark gap before removing anything.
4. Remove — Disconnect the high-voltage lead and unscrew the old electrode from the burner assembly.
5. Install — Mount the new electrode at the correct gap and orientation, then reconnect the ignition lead per your photo.
6. Test — Restore gas and power, then confirm a strong spark, clean light-off, and stable flame on a heat call.

Signs You Need a Replacement

• No spark at the burner on a call for heat.
• Delayed or rough ignition with a loud light-off.
• Repeated ignition lockouts after several failed attempts.
• Cracked ceramic insulator or carbon-fouled, eroded electrode tip.
