ICP Hot Surface Igniter Electrode for RGS243STAA0AAAA — OEM 1179966 | Ships Today

Overview

The ICP igniter electrode (OEM part 1179966) is the genuine hot surface igniter for the RGS243STAA0AAAA gas furnace. On each call for heat, the control board energizes the igniter, which glows red-hot to ignite the gas at the burners. Hot surface igniters are brittle and degrade with every heating cycle — a cracked, oxidized, or open igniter is one of the most common causes of furnace no-heat calls. This OEM electrode is dimensionally and electrically matched to the RGS243, ensuring proper glow temperature, correct flame proving, and reliable ignition.

Specifications

Compatibility

Direct-fit OEM igniter for the ICP/Tempstar/Heil RGS243STAA0AAAA gas furnace. This is the factory-specified hot surface igniter for this model. Handle the silicon-carbide element by the ceramic base only — never touch the glow element with bare fingers.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, and shut off the gas supply. Verify zero voltage with a multimeter.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter's position and wiring before disconnecting.
4. Remove — Unplug the igniter harness and remove the mounting screw(s), then withdraw the old igniter carefully without touching the new element.
5. Install — Mount the new igniter by the ceramic base only, align it to the burner per your photo, and reconnect the harness.
6. Test — Restore gas and power, call for heat, and confirm the igniter glows and lights the burners cleanly.

Signs You Need a Replacement

• Furnace blower runs but burners never light (no heat)
• Igniter no longer glows or glows weakly
• Visible cracks or white oxidation on the element
• Open circuit / infinite resistance reading across the igniter
