ICP Ignitor Electrode for RGS303SSAA0AAAA — OEM 1179966 | Ships Today

Overview

This is a genuine OEM ignitor electrode, part number 1179966, for ICP, Tempstar, and Heil gas furnaces. The electrode delivers the spark that lights the burner gas at the start of every heating cycle and, in many designs, also senses the resulting flame to confirm successful ignition. Because it sits directly in the burner flame path, the electrode tip and its ceramic insulator endure repeated thermal cycling and gradually crack, erode, or carbon-foul. When the electrode degrades you will see ignition lockouts, repeated ignition retries before the burner lights, delayed or rough light-off, or the furnace dropping out shortly after ignition because flame can no longer be sensed. Installing a fresh OEM electrode restores a strong, consistent spark and reliable flame confirmation.

Specifications

Compatibility

Built as the factory-specified ignitor electrode for the ICP Tempstar Heil RGS303SSAA0AAAA gas furnace and other ICP-family models using the same burner assembly. Confirm the bracket and electrode geometry match your existing part before installing.

Installation Guide

1. Safety First — Shut off the gas supply, disconnect power at the breaker, and verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment service panel.
3. Document — Photograph the electrode position, gap, and wire routing before removing anything.
4. Remove — Disconnect the ignition lead, unscrew the electrode bracket from the burner assembly, and lift it out.
5. Install — Mount the new electrode at the same position and gap, then reconnect the ignition lead per your photo.
6. Test — Restore gas and power, start a heat cycle, and confirm a strong spark and stable flame on first try.

Signs You Need a Replacement

• Furnace locks out on failed ignition
• Multiple ignition retries before the burner lights
• Cracked or eroded ceramic insulator at the electrode
• Furnace drops out seconds after the burner lights (lost flame sense)
