ICP Ignitor Electrode for RGS303SEEA0AAAA — OEM 1179966 | Ships Today

Overview

This genuine OEM ignitor electrode (part number 1179966) for ICP, Tempstar, Heil, and Comfortmaker gas furnaces delivers the spark that lights the burner at the start of every heat cycle. The electrode's ceramic insulator and precisely gapped metal tip create the high-voltage arc that ignites gas at the burner. Over time the tip erodes, cracks, or carbons over, causing failed ignition, repeated retries, or a furnace that locks out on no-flame. Because it also sits in the flame field, a degraded electrode can disrupt flame sensing and cause short-cycling. Installing a fresh OEM electrode restores fast, dependable light-off.

Specifications

Compatibility

Designed for the ICP/Tempstar/Heil RGS303SEEA0AAAA gas furnace and related RGS303-series models that originally used electrode 1179966. Confirm the part number and bracket geometry against your existing electrode before ordering.

Installation Guide

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

Signs You Need a Replacement

• Furnace clicks but the burner won't light.
• Repeated ignition retries or hard lockout on no-flame.
• Cracked ceramic insulator or visibly eroded electrode tip.
• Weak, intermittent, or yellow/orange spark.
