ICP Ignitor Electrode for RGS303SFAA0AAAA — OEM Direct Spark | Ships Today

Overview

This OEM ignitor electrode (ICP part #1179966) is the ignition component that creates the spark or ignition point used to light the burners in your RGS303SFAA0AAAA furnace. The electrode is positioned at the burner and, on each heat call, provides the precise gap and ceramic insulation needed to ignite the gas reliably. Over time the electrode tip can crack, erode, carbon-foul, or shift out of gap, leading to delayed ignition, repeated lockouts, or no heat at all. Because ignition components are exposed to direct flame and thermal cycling, they are a common wear item. Installing the exact OEM electrode restores correct gap geometry and dependable light-off, helping avoid nuisance lockouts and protecting the heat exchanger from unburned-gas events.

Compatibility

Factory replacement ignitor electrode for ICP / Tempstar / Heil model RGS303SFAA0AAAA and related ICP-family gas furnaces using this electrode. Verify OEM number 1179966 and the electrode bracket/gap against your existing part before ordering.

Installation Guide

1. Safety First — Shut off the gas, disconnect power, and verify zero voltage with a multimeter.
2. Access — Remove the burner/service panel to reach the ignition area.
3. Document — Photograph the electrode position, wiring, and gap before removing.
4. Remove — Disconnect the ignition lead and unscrew the electrode bracket from the burner assembly.
5. Install — Mount the new electrode, set the correct gap per the furnace spec, and reconnect the ignition lead.
6. Test — Restore gas and power, then confirm clean, prompt ignition on a heat call.

Signs You Need a Replacement

• Delayed ignition or audible "whoomp" on light-off
• Repeated ignition lockouts / no heat
• Cracked ceramic insulator or eroded electrode tip
• Weak, intermittent, or no spark at the burner
