ICP Spark Igniter (Ignitor/Sparker) for RGS180LSAA0AAAA — Ships Today

Overview

This genuine OEM spark igniter (part number 1184216, "IGNITOR SPARKER") provides the high-voltage spark that lights the burners on the ICP/Tempstar/Heil RGS180LSAA0AAAA gas furnace. On a heat call, the control board sends voltage to the igniter, which arcs across its electrode gap to ignite the gas at the burner. Unlike a hot surface igniter that glows, this is a direct-spark style component, so a worn electrode, cracked ceramic insulator, or carbon buildup on the tip will cause no-light or delayed-ignition faults. Typical symptoms are a furnace that clicks but won't fire, repeated ignition lockouts, intermittent heat, or burners that light with a delayed "whoomph."

Specifications

Compatibility

Engineered for the ICP RGS180LSAA0AAAA and related ICP/Heil/Tempstar/Comfortmaker gas furnaces that use this direct-spark ignition assembly. Verify the electrode shape and mounting bracket match your existing igniter before installing.

Installation Guide

1. Safety First — Shut off the gas supply and disconnect electrical power; verify zero voltage with a multimeter.
2. Access — Remove the furnace burner-compartment door.
3. Document — Photograph the igniter position, gap, and wire routing before removal.
4. Remove — Disconnect the ignition lead, remove the mounting screw(s), and lift out the old igniter without touching the ceramic with bare fingers.
5. Install — Mount the new igniter, restoring the factory electrode gap, and reconnect the ignition lead.
6. Test — Restore gas and power, run a heat cycle, and confirm a strong spark and clean burner light-off.

Signs You Need a Replacement

• Furnace clicks/sparks but burners won't ignite.
• Repeated ignition lockout or error codes.
• Cracked ceramic insulator or eroded electrode tip.
• Delayed ignition with a rough or loud light-off.
