ICP Hot Surface Igniter Electrode for RGS303HDEA0AAAA — OEM | Ships Today

Overview

This OEM ignitor electrode (part 1179966) is the factory ignition component for ICP / Heil / Tempstar model RGS303HDEA0AAAA. The electrode is responsible for lighting the main burners on each heating cycle. On a call for heat, the control board powers the igniter to produce the spark or hot surface that ignites the gas. A cracked element, eroded tip, or hairline fracture in the electrode prevents light-off, leading to no heat, repeated ignition lockouts, or a furnace that cycles on the limit. Replacing with the exact OEM electrode restores fast, dependable burner ignition.

Specifications

Compatibility

Designed for ICP / Heil / Tempstar model RGS303HDEA0AAAA and platform-shared furnaces using this ignition electrode. Confirm the mounting bracket and lead connector match your existing igniter before installing.

Installation Guide

1. Safety First — Shut off gas and disconnect power; verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position, gap, and wiring before removal.
4. Remove — Disconnect the igniter lead and unscrew the electrode from the burner assembly; handle the element only by its base.
5. Install — Mount the new OEM electrode without touching the element, set the proper gap, and reconnect the lead.
6. Test — Restore gas and power and confirm clean burner ignition on a call for heat.

Signs You Need a Replacement

• No heat — burners won't light on a call
• Repeated ignition lockouts or short cycling
• Visible crack, erosion, or carbon buildup on the element
• Delayed ignition with a small "poof" at light-off
