ICP Igniter Electrode for RGS300LDFA0AAAA — Direct Ignition | Ships Today

Overview

This OEM igniter electrode (part number 1179966) provides the ignition spark that lights the burners in your ICP Tempstar Heil RGS300LDFA0AAAA furnace. The electrode positions a precise gap at the burner so that, on a heat call, it generates the high-voltage arc needed to ignite the gas. A cracked ceramic insulator, an eroded electrode tip, or a misaligned gap will cause no ignition, repeated ignition lockouts, or delayed/rough light-off. Replacing this small but critical part restores reliable, on-demand heating.

Specifications

Compatibility

Designed for the ICP Tempstar Heil RGS300LDFA0AAAA and related RGS-series gas furnaces that use this direct-ignition electrode assembly. Confirm the electrode shape and mounting match your existing part.

Installation Guide

1. Safety First — Shut off gas and disconnect power at the furnace switch; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the electrode position, gap, and wire routing before removing.
4. Remove — Disconnect the high-voltage ignition lead and unscrew the electrode from the burner assembly.
5. Install — Mount the new electrode, restore the proper gap, and reconnect the ignition lead per your photo.
6. Test — Restore gas and power, then verify a clean spark and burner light-off on a heat call.

Signs You Need a Replacement

• No spark or no burner ignition on a heat call
• Repeated ignition lockouts or short cycling
• Cracked or chipped ceramic insulator
• Eroded or burned electrode tip
