ICP Ignitor Electrode for RGS300SEEA0AAAA — Spark Ignition OEM 1179966 | Ships Today

Overview

This is the genuine OEM ignitor electrode, ICP part number 1179966, specified for the ICP/Tempstar/Heil RGS300SEEA0AAAA gas furnace. The electrode delivers the high-voltage spark that lights the burner at the start of each heat cycle and, on many designs, also serves as the flame-sense path that proves the burner has lit. Because the electrode sits directly in the burner flame, its tip and ceramic insulator degrade over time — cracking, eroding, or carbon-fouling. The result is failed ignition, repeated lockouts, or short cycling. Installing the correct OEM electrode restores a reliable spark gap and clean flame signal.

Specifications

Compatibility

Direct OEM replacement for the ICP/Tempstar/Heil RGS300SEEA0AAAA gas furnace, and a fit for related ICP-family furnaces that use the 1179966 ignitor electrode. Confirm your existing electrode part number and bracket orientation before ordering.

Installation Guide

1. Safety First — Shut off the gas, disconnect power at the switch and breaker, then 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 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 and reconnect the ignition lead per your photo. Do not touch the ceramic with oily hands.
6. Test — Restore gas and power, then watch for a strong spark and stable burner ignition.

Signs You Need a Replacement

• No spark or weak/intermittent spark at startup.
• Furnace locks out after several failed ignition attempts.
• Cracked ceramic insulator or eroded electrode tip.
• Burner lights then drops out on flame-sense failure.
