ICP Igniter Electrode for RGS243SEEA0AAAA — Direct Ignition | Ships Today

Overview

This OEM igniter electrode (part #1179966) lights the burners on your ICP/Tempstar/Heil RGS243SEEA0AAAA gas furnace. When the control board calls for heat, the electrode delivers the high-voltage spark that ignites gas at the burner and then provides flame rectification to confirm a stable flame. A cracked ceramic insulator, eroded electrode tip, or carbon buildup will cause the furnace to fail ignition, lock out, or short-cycle. Because the electrode also senses flame, a degraded tip can make the board think the flame went out and shut the gas valve mid-cycle. Replacing this low-cost wear part restores reliable, on-demand ignition and prevents nuisance lockouts during cold weather.

Specifications

Compatibility

Direct factory replacement for the ICP/Tempstar/Heil RGS243SEEA0AAAA gas furnace and other models using electrode part #1179966. Verify the mounting bracket and electrode gap match your existing part.

Installation Guide

1. Safety First — Shut off gas and disconnect furnace power; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner compartment door.
3. Document — Photograph the electrode position, gap, and wire routing 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 gap per your photo, and reconnect the lead.
6. Test — Restore gas and power, call for heat, and confirm clean spark, ignition, and a stable flame signal.

Signs You Need a Replacement

• Furnace fails to ignite or locks out after several attempts
• Cracked or chipped ceramic insulator
• Weak, erratic, or no spark at the burner
• Short-cycling caused by lost flame sensing
