ICP Ignitor Electrode for RGS240HRAA0AAAA — Spark Ignition | Ships Today

Overview

This OEM ignitor electrode (ICP part 1179966) lights the burners on the ICP / Heil / Tempstar RGS240HRAA0AAAA gas furnace. The electrode produces the high-voltage spark that ignites gas at the burner and, on many configurations, also senses flame to confirm ignition. A cracked ceramic insulator, eroded electrode tip, or wrong spark gap leads to delayed ignition, repeated ignition lockouts, or a furnace that clicks but never lights. Replacing a worn electrode restores fast, reliable lights and prevents nuisance no-heat lockouts during cold weather.

Specifications

Compatibility

Direct-fit for the ICP / Heil / Tempstar RGS240HRAA0AAAA furnace and related Comfortmaker-family models that use electrode 1179966. Confirm the part number and bracket shape against your existing electrode before ordering.

Installation Guide

1. Safety First — Shut off the gas, disconnect power at the switch and breaker, and verify zero voltage with a multimeter.
2. Access — Remove the furnace burner/service panel.
3. Document — Photograph the electrode position, wire routing, and spark gap before removing.
4. Remove — Unplug the ignition lead and unscrew the electrode from the burner assembly.
5. Install — Mount the new electrode, set it in the factory position, and reconnect the ignition lead per your photo.
6. Test — Restore gas and power, then run a heat cycle to confirm a strong spark and clean burner light.
