ICP Hot Surface Igniter Electrode for RGS183HDAA0AGAA — Furnace Ignition | Ships Today

Overview

This OEM hot surface igniter electrode (#1179966) is the ignition source for the ICP/Tempstar/Heil RGS183HDAA0AGAA gas furnace. On each heat call the control board sends voltage to the igniter, which glows to a high temperature and lights the burner gas. Hot surface igniters are a wear item — the brittle element naturally degrades from repeated thermal cycling, and cracks or hairline fractures stop the furnace from lighting. If your furnace clicks, draws air, but never fires, the igniter is the first part to check.

Specifications

Compatibility

Designed for the ICP/Tempstar/Heil RGS183HDAA0AGAA gas furnace and matched models using this electrode-style hot surface igniter. Confirm the mounting bracket and connector against your existing part.

Installation Guide

1. Safety First — Disconnect power at the furnace switch and breaker, verify zero voltage with a multimeter, and shut off the gas.
2. Access — Remove the burner compartment service panel.
3. Document — Photograph the igniter position, wiring, and connector orientation before disconnecting.
4. Remove — Unplug the igniter connector and remove the mounting screw; handle the old element only by the ceramic base.
5. Install — Mount the new igniter without touching the element with bare fingers, then reconnect per your photo.
6. Test — Restore gas and power, start a heat call, and confirm the igniter glows and the burner lights.

Signs You Need a Replacement

• Furnace runs the ignition sequence but never lights
• Visible cracks, chips, or breaks in the igniter element
• Igniter does not glow on a heat call
