ICP Spark Igniter for RGS180LEAA0AAAA — OEM Ignitor Sparker 1184216 | Ships Today

Overview

This is a genuine OEM spark igniter (ignitor sparker), ICP part number 1184216, for the ICP / Tempstar / Heil RGS180LEAA0AAAA gas furnace. The spark igniter generates the high-voltage arc that lights the burner gas at startup. When this component fails, the furnace will call for heat, the inducer and gas valve may cycle, but the burners never light — leaving you with no heat and often a hard-lockout fault on the control board. A cracked ceramic insulator, eroded electrode, or carbon buildup on the tip are the most common failure modes, especially in older units that have gone through many ignition cycles.

Specifications

Compatibility

Engineered for the ICP / Tempstar / Heil RGS180LEAA0AAAA gas furnace and other RGS-series models that use the 1184216 igniter assembly. Always confirm the part number against your existing igniter before ordering.

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 furnace blower/burner service panel.
3. Document — Photograph the igniter position and wiring before disconnecting.
4. Remove — Unplug the igniter lead and remove the mounting screw(s); carefully withdraw the old igniter from the burner assembly.
5. Install — Seat the new 1184216 igniter at the correct gap to the burner, fasten, and reconnect the lead per your photo.
6. Test — Restore gas and power, then run a full heat cycle and confirm a clean, reliable light-off.

Signs You Need a Replacement
