ICP Ignitor Electrode for RGS210SDEA0AAAA — Direct Ignition (1179966) | Ships Today

Overview

This OEM ignitor electrode (part #1179966) is the spark/sensing electrode for ICP, Heil, and Tempstar gas furnaces. It delivers the high-voltage spark that lights the burner on a call for heat and, on many designs, also provides flame rectification so the control board can confirm a flame is present. A cracked ceramic insulator, a corroded or eroded electrode tip, or a misaligned gap leads to ignition lockout, delayed ignition, or short cycling on flame failure. Replacing a worn electrode restores reliable, on-demand ignition.

Specifications

Compatibility

Direct OEM replacement for ICP/Heil/Tempstar model RGS210SDEA0AAAA and related furnaces using this spark ignition electrode. Match the part number and bracket orientation to your existing electrode before installing.

Installation Guide

1. Safety First — Disconnect power and shut off the gas supply; verify zero voltage with a multimeter.
2. Access — Remove the burner-compartment door.
3. Document — Photograph the electrode position, gap, and wire routing before removal.
4. Remove — Disconnect the ignition lead and unscrew the electrode bracket from the burner assembly.
5. Install — Mount the new electrode, confirm the spark gap, and reconnect the high-voltage lead.
6. Test — Restore gas and power, then verify clean spark and burner ignition on a heat call.

Signs You Need a Replacement

• Furnace locks out with no ignition
• Delayed ignition or rough light-off
• Cracked ceramic insulator or corroded tip
• Short cycling on flame-sense failure
